January 2022—Laboratories don’t have to monitor direct oral anticoagulants, but they might want to measure DOAC drug levels in some situations in some patients, said Karen A. Moser, MD, in a CAP21 session.

October 2021—Clonal hematopoiesis is a significant biological phenomenon and denotes presence of mutations in bone marrow stem cells in the absence of a hematologic malignancy.

October 2021—Rules, slide reviews, test ordering, and provider education were part of the conversation when CAP TODAY publisher Bob McGonnagle convened a hematology-focused virtual roundtable in late August. Workforce problems too: “We have a bigger exodus now and our pipeline is smaller,” said Eric D. Hsi, MD, of Wake Forest University.  

September 2021—Rare wine? Delectable. Rara avis? Magnificent. Rare blue-top collection tube? Uh oh. For Richard Marlar, PhD, coming across a non-FDA-approved tube was an unhappy discovery. Dr. Marlar, medical director, coagulation laboratory, University of New Mexico Hospital, says his lab was among the first to encounter one of these rogue tubes, available for purchase on the internet and likely taking wing due to pandemic supply shortages. When the tube arrived for testing, it quickly kindled concerns, says Dr. Marlar. “It’s a tube we had never seen before. It looks like it has a CE mark on it, and the Europeans don’t know anything about it. It has a label on it that suggests it’s FDA approved—but the FDA is not aware of it,” he says, adding that his lab has spoken with the agency. It feels like a “CSI”-tinged moment in a venue that labs would prefer to keep drama-free. It also points to the ongoing need to keep a keen eye on what passes through coagulation laboratories. It’s not so much that the devil is in the details; rather, that’s where accurate results lie.

August 2021—Platelet function testing using platelet-rich plasma is the gold standard, but whole blood platelet aggregation has its advantages, with less risk for preanalytic error among them.

July 2021—The pandemic’s reach has often been portrayed in shades of red, signaling surging COVID-19 cases across states and countries. Vaccination maps, on the other hand, tend to render progress in more soothing tones, typically in the green family. But in coagulation laboratories, one small portent is colored blue—specifically, blue-top sodium citrate tubes. In recent months, laboratories began voicing concerns about tightening supplies. They’ve spoken with their vendors; some have reached out to new ones. And though no one wants to think about limiting testing if supplies truly become scarce, it wouldn’t be the first time labs have had to steer through these waters. The tubes are a functional symbol of the continued complexities of COVID-19-related coagulopathy, as physicians try to understand and respond to the pathophysiology of infection that leads to a thrombotic event. As the pandemic has churned on, much has started coming into sharper focus. Prepublication persists, but physicians have begun to sort through the past 18 months and, as many have put it, to “do the science.”
