Waste in PCR laboratories can add up quickly, leading to unnecessary expenses. From reagent loss to inefficiencies in equipment use, addressing these issues is crucial for maintaining operational efficiency and cutting costs.

Here are three practical strategies to minimize waste and optimize your lab’s resources:

1. Vortex and Centrifuge Properly

One common source of waste comes from improper handling of reagents. When reagents aren’t fully mixed and settled, valuable liquid often gets stuck inside the caps of tubes, leading to waste. To avoid this, it’s essential to vortex reagents first to ensure everything is thoroughly mixed, followed by centrifuging to pull all liquid to the bottom of the tube.

Solution:
Make it a routine to vortex reagents thoroughly before centrifuging. This ensures all material is mixed and settles correctly, reducing the chance of reagent sticking to the cap and getting wasted.

2. Use Calibrated Pipettes and Quality Tips

Even the smallest inefficiencies in pipetting can result in reagent waste. When pipettes aren’t calibrated or if low-quality tips are used, adhesion can cause reagents to remain inside the tip, meaning you’re not dispensing the full amount. Over time, this incomplete dispensing adds up, leading to significant reagent loss.

Solution:
Ensure that your pipettes are regularly calibrated for accuracy and invest in high-quality pipette tips that minimize adhesion. These adjustments ensure you get the full volume of reagent every time, reducing waste and saving on reagent costs.

3. Switch from Pre-Plated to Liquid Reagents or Breakaway Plates

Pre-plated reagents offer convenience, but if your lab’s testing volumes fluctuate, they can lead to unnecessary waste. When you don’t need to use an entire plate, the excess reagents go unused and are often discarded. This is especially problematic if your lab regularly runs smaller volumes.

Solution:
Switch to a liquid reagent format for greater flexibility, especially if your lab uses 384-well plates, which support higher throughput. Alternatively, you can opt for breakaway pre-plated wells, allowing you to use only what you need, reducing waste.

Conclusion

By making simple adjustments—vortexing and centrifuging properly, using calibrated pipettes and quality tips, and switching reagent formats—your PCR lab can significantly reduce waste and optimize its operations. These changes may seem small, but they can have a substantial impact on your lab’s efficiency and cost savings over time.

For PCR labs, efficiency and cost management are critical to staying competitive. As a manufacturer of PCR infectious disease reagents and a lab operator, I’ve seen firsthand what gives some labs a distinct edge. Two key factors can drastically improve throughput without incurring additional costs: equipment setup and reagent selection.

1. The Power of Equipment Setup: 96 vs. 384 Well Formats

PCR labs typically use either 96 well or 384 well plates. Both formats offer virtually identical costs per run in terms of consumables, but the 384 well format can provide four times the throughput. The difference here is scalability.

• 96 well format: Easier to handle with manual pipetting and allows access to breakaway pre-plated options. However, scaling up requires more resources.
• 384 well format: A single 384 well machine can match the throughput of four 96 well machines, meaning you’ll only need one machine instead of four. This means fewer validations, reduced consumable use, and significantly higher throughput without an increase in operational costs.

For example, our lab uses 384 well machines because they offer flexibility and scalability without additional overhead. The upfront costs of both systems are comparable, but the long-term scalability of 384 well machines makes it a clear winner when it comes to managing higher volumes efficiently.

2. Reagents and Multiplexing

Another major factor in optimizing throughput is the use of multiplexing reagents. Multiplexing allows you to run multiple tests within a single well, greatly reducing the number of wells required for each sample.

Take the example of Influenza A/B, COVID, and RSV, which I call a “Mini-RPP” panel. Using singleplex reagents, it would take four wells to complete this test. However, with multiplexing, you can complete the same test in one or two wells.

Let’s compare two labs:

• Lab 1:
  • Uses 96 well plates and singleplex reagents
  • Can perform 22 Mini-RPP tests (after accounting for controls)
• Lab 2:
  • Uses 384 well plates and multiplexing reagents
  • Can perform 172 Mini-RPP tests per run

The difference is clear: Lab 2 can handle 8 times more testing in the same amount of time, using the same consumables and reagents.

Why This Matters

Labs using 384 well setups combined with multiplexing reagents can dramatically increase their throughput, lower operational costs, and reinvest those savings into future growth. This gives them a huge advantage over labs that stick to 96 well machines and singleplex reagents.

Conclusion: Unlocking Efficiency for PCR Labs

If you’re looking to optimize your lab’s capacity and reduce costs, consider transitioning to a 384 well format and multiplexing reagents. These two factors alone can transform your lab’s efficiency, allowing you to handle more tests without needing extra equipment, staff, or consumables.

Respiratory Testing Surge in 2024-2025 The 2024-2025 respiratory season is expected to drive a 10-15% increase in testing volume for influenza, RSV, and COVID-19. Flu testing alone is anticipated to hit 15-20 million tests, a surge from last year’s figures, with RSV tests expected to top 5 million. This rise is driven by returning virus activity to pre-pandemic levels, coupled with increased awareness due to new RSV vaccines targeting infants and senior citizens.

While COVID-19 testing remains lower than its pandemic peak, labs should still prepare for around 10 million tests, particularly in areas where cases might surge during the winter.

The Growing Crisis

Newborn syphilis cases have increased drastically in the U.S., with the number of affected infants rising tenfold between 2012-2022. In 2022, 3,761 babies were born with syphilis, a preventable condition if appropriate prenatal care and testing were implemented. The rise in congenital syphilis is directly linked to the increased prevalence of syphilis among reproductive-age women, barriers to healthcare access, and the disproportionate impact on minority communities.

How Labs Can Respond

Laboratories can play a critical role in mitigating this public health crisis by enhancing their testing capabilities, expanding access, and partnering with healthcare providers to support early detection and treatment of syphilis in pregnant women. Here are some actionable steps for labs:

1. Expand Access to Syphilis Testing
   To address the gap in testing, labs should target high-incidence areas, especially those where prenatal care is often delayed or inaccessible. Expanding services through community partnerships, mobile testing units, or telehealth solutions can make testing more convenient for high-risk populations.
2. Partner with Public Health Initiatives
   Labs can collaborate with public health departments and community health workers to enhance outreach and education. These partnerships can help target vulnerable populations, offering testing and treatment in locations where healthcare access is limited.
3. Support Telehealth and At-Home Testing
   With the ongoing expansion of telehealth, labs can develop at-home syphilis testing kits, allowing patients to get tested without needing to visit a clinic. This can be particularly effective for reaching people in rural or underserved areas where in-person visits might be difficult.
4. Promote Preventative Screening
   Proactively offering screening to women of reproductive age and their partners in areas with high syphilis rates can reduce the number of newborn infections. Labs can support routine screening efforts by promoting regular tests at every stage of pregnancy, especially in the first and third trimesters.

Building a Public Health Response

The sharp increase in congenital syphilis cases, driven by lack of prenatal care and systemic barriers, underscores the need for labs to be at the forefront of testing and diagnosis. By improving access to testing, offering rapid diagnostics, and collaborating with healthcare providers, labs can be pivotal in preventing the transmission of syphilis from mothers to newborns.

Conclusion

Laboratories have a significant role to play in reversing the trend of rising congenital syphilis cases. By expanding testing capabilities and working closely with public health initiatives, labs can help protect the most vulnerable populations and ensure that preventable diseases like syphilis no longer threaten the health of newborns.

Current Mpox Situation
As of September 2024, Mpox continues to be a concern in the U.S., although case numbers have decreased significantly from the initial outbreak in 2022-2023. While widespread outbreaks have been contained, localized clusters persist, primarily among high-risk populations,such as individuals with multiple sexual partners. Public health efforts remain focused on monitoring and containment.

Testing Demand in 2024
Although testing demand is no longer as intense as during the peak of the outbreak, it remains steady in areas with ongoing transmission. The CDC has scaled up testing capabilities to ensure rapid detection, with up to 80,000 tests available per week. Public health agencies continue to emphasize the importance of testing in high-risk populations to prevent further spread

Adding Mpox PCR Testing: Is It Feasible?
For labs already conducting PCR testing for other infectious diseases, adding Mpox PCR is a relatively easy and cost-effective option. The FDA has authorized multiple Mpox PCR tests, and integrating them into an existing PCR setup does not require significant investment. Moreover, the demand for Mpox testing may provide labs with an opportunity to serve their communities and high-risk groups

For labs without existing PCR capabilities, however, the cost of setting up PCR infrastructure can be prohibitive. The necessary investment in equipment, staff training, and regulatory compliance may not be justified, especially since Mpox outbreaks have been largely contained. Labs considering this expansion should carefully evaluate local testing demand before making a decision

Conclusion
If your lab already offers PCR testing, adding Mpox PCR testing could be a strategic move to address niche demand in your community. However, for labs without this capacity, the cost may outweigh the benefits unless there is a significant local need for Mpox testing.

However, new equipment also comes with a higher upfront cost, which may be a concern for labs working with limited budgets.

Advantages of Used Lab Equipment:

• Lower Initial Cost: Used lab equipment tends to be more affordable, allowing labs to acquire high-quality instruments at a fraction of the price of new equipment. This can free up funds for other areas of your lab’s operations or expansion.
• Slower Depreciation: Used equipment has already experienced the steepest depreciation, so it retains more of its value over time. This can be beneficial if you plan to resell or upgrade in the future.
• Access to Discontinued Models: Some labs may find that older, discontinued models are a perfect fit for their needs. The used market offers access to specialized equipment that may no longer be available, allowing you to continue using preferred instruments.

However, the downsides to used equipment include the potential for limited warranty or unknown maintenance history, which can pose risks to long-term performance.

Which Should You Choose?

The decision between new and used equipment depends on your specific needs and risk tolerance. If cutting-edge technology, reliability, and warranties are crucial for your lab, investing in new equipment may be the best option. On the other hand, if you’re looking to save on upfront costs while still acquiring high-quality instruments, used equipment can provide excellent value—especially if you work with a reputable vendor that offers certified or refurbished products.

By carefully evaluating your lab’s priorities and budget, you can make an informed decision that aligns with your operational goals.

In the lab industry, staying competitive requires continuous improvements in efficiency and service offerings. Whether your lab is small or large, here are three strategies that can help boost competitiveness while minimizing operational costs:

1. Increase Throughput with High-Capacity Setups

One of the most effective ways to enhance your lab’s competitiveness is by increasing throughput without significantly increasing operating costs. For example, in PCR labs, switching from a 96-well plate to a 384-well plate can quadruple your throughput without any added reagent or consumable cost. This results in faster turnaround times and greater testing capacity, all while keeping operational costs stable.

In addition, upgrading from single-channel to multi-channel pipettes can speed up sample preparation, allowing your lab to process more samples in less time. This setup works for both small labs and large facilities looking to maximize efficiency without major upfront investment.

2. Offer Comprehensive Testing Panels to Broaden Your Client Base

Instead of focusing on individual tests, offering comprehensive testing panels can help your lab appeal to a wider range of clients. By validating a single test panel that covers multiple targets—such as respiratory pathogens or a broader infectious disease panel—you can service a more diverse client base without the need for multiple validations.

This not only positions your lab as a flexible, full-service provider but also allows you to be more efficient with the resources and processes you already have in place.

3. Quick, Flexible Changes for Long-Term Gains

Sometimes the smallest changes can make the biggest difference. Consider:

• Optimizing sample management workflows by reducing manual steps and digitizing tracking.
• Switch to reagents that have faster run times to become an ideal choice for providers.
• Cross-training staff to ensure greater flexibility in handling different tasks during peak times.

Cash flow is critical for the smooth operation of any lab, and managing it effectively can be challenging. A key area where labs can optimize cash flow is in consumables—especially reagents, which often represent a large portion of the budget. Here are two strategies to improve cash flow without sacrificing quality:

1. Evaluate the True Cost of Reagents

When purchasing reagents, many labs focus on the cost-per-test or reaction, but it’s essential to consider the true cost after accounting for waste. Although a kit may advertise 100 reactions, factors such as pipetting loss and testing inefficiencies mean you may be getting fewer usable reactions than expected. Over time, this can significantly inflate your actual cost per patient.

To optimize cash flow:

• Monitor actual reagent usage in relation to the number of successful tests and adjust ordering practices to minimize waste.
• Implement precise pipetting techniques or consider investing in automated systems to reduce human error and minimize reagent loss.
• Consolidate testing where possible to fully utilize reagent batches and reduce the frequency of partial kit use, which often leads to excess waste.

By understanding the actual cost per usable reaction, your lab can make better purchasing decisions and reduce overspending on consumables.

2. Leverage Bulk Purchasing Strategically

Bulk purchasing can be a cost-saving strategy, but only when done wisely. Labs should focus on bulk buying items that have long shelf lives or are consistently used. For items with shorter expiration periods, it’s important to partner with suppliers who can offer bulk discounts along with flexible, smaller quantity deliveries.

Another strategy is to form alliances with other labs to pool purchasing power and negotiate better deals on shared supplies, allowing you to benefit from bulk discounts without overstocking.

By focusing on these strategies, labs can optimize their operational costs, reduce waste, and improve cash flow without sacrificing the quality of their services.
