A major shift in cervical cancer screening is here—and clinical laboratories will play a pivotal role.

Earlier this month, HRSA released its first major update to evidence-based cervical cancer screening guidelines in nearly a decade, signaling a clear move toward primary high-risk HPV (hrHPV) testing as the preferred option for women ages 30–65.

Key takeaways for lab professionals:
• Primary hrHPV testing every 5 years is now preferred for average-risk women 30–65
• HPV self-collection is explicitly endorsed as an acceptable option for certain groups
• Co-testing with cytology remains acceptable when hrHPV testing isn’t available
• Follow-up testing without cost sharing (including dual stain, genotyping, colposcopy) begins in 2027

Why it matters: hrHPV testing offers higher sensitivity for detecting precancer—and expanded access options like self-collection could help close screening gaps for underserved populations.

As screening models evolve, labs will be central to ensuring accuracy, access, and continuity across the diagnostic pathway.

Will 2026 bring relief—or more uncertainty—for clinical laboratory reimbursement?

That question took center stage during a January 8 House Energy & Commerce Subcommittee hearing on Medicare payment policy and the proposed RESULTS Act.

Testimony from ACLA highlighted why many labs say the current PAMA framework isn’t working: outdated data, ongoing reimbursement cuts, and a reporting burden that pulls focus from patient care. Since 2018, Medicare lab payments have been reduced far beyond original projections—and more cuts are looming.

The RESULTS Act aims to change course by:
• Using broader, more current commercial market data
• Easing reporting requirements for most labs
• Freezing CLFS rates temporarily to stabilize the system
• Capping future payment reductions

In this MLO update, Editor-in-Chief Christina Wichmann outlines what happened at the hearing, what’s in the legislation, and why another short-term PAMA delay is likely before long-term reform takes hold.

Despite 140 years of scientific progress, TB is once again the world’s leading infectious disease killer. And many of its biggest mysteries—and solutions—still live in the lab.

Our December Continuing Education article explores why TB remains so difficult to detect, how the disease exists on a spectrum (not just “latent” vs. “active”), and why early, accurate laboratory diagnosis is one of the most powerful tools we have to stop transmission.

🔬 In this CE article, you’ll learn how to:
• Interpret global and U.S. TB epidemiology
• Understand TB transmission and disease states
• Compare TB testing methodologies (TST vs. IGRA) and their limitations
• Explore innovations shaping the future of TB diagnostics

The takeaway? Labs aren’t just supporting players—we’re strategic partners in TB elimination.

A patient looks stable. The vitals are reassuring. The SOFA score is low.
So why do some patients suddenly deteriorate hours later?

A new Medical Laboratory Observer online exclusive explores how estimated plasma volume (ePV)—calculated from hemoglobin and hematocrit—can reveal hidden risk before clinical decline becomes obvious.

In one real-world case, an elevated ePV signaled early sepsis and volume overload in a patient who initially appeared well.

The article breaks down:

🔬Why traditional volume assessments often conflict

🔬How ePV provides a low-cost, scalable marker of intravascular congestion

🔬Growing evidence for ePV’s prognostic value in sepsis, heart failure, ARDS, COPD, and COVID-19

🔬What this means for labs, intensivists, and respiratory care teams making real-time decisions

What does it take to keep pace with rapidly evolving diagnostics—from H5N1 and dengue to HIV differentiation and optical genome mapping?

We spoke with Dr. Joel Todd Moncur, Chair of the CAP’s Council on Scientific Affairs, about the 21 new PT/EQA programs launching in 2026—and how they’re designed to strengthen quality, accuracy, and confidence across the lab.

Here’s what stood out:
• New H5N1 influenza A and Dengue Virus Serology programs supporting U.S. and global laboratories.
• The first global HIV-1/HIV-2 molecular detection and differentiation PT program.
• Tools to help labs verify analytical measurement range—including reticulocyte calibration verification.
• Programs built to reflect today’s testing realities and tomorrow’s diagnostic challenges.

As labs face increasing complexity, proficiency testing is more than a compliance exercise—it’s a roadmap for continuous quality improvement.
