Q&A column

May 2023
Q. How long do blood transfusions affect mean corpuscular volume values? A patient had a red blood cell count of 2.5 × 106/μL, hemoglobin level of 7.3 g/dL, hematocrit of 22.7 percent, MCV of 90.8 fL, mean corpuscular hemoglobin of 29.2 pg/cell, and a mean corpuscular hemoglobin concentration of 32.2 g/dL. Thirteen days after transfusion, the patient’s values were an RBC of 3.61 × 106/μL, Hgb 10.7 g/dL, Hct 34.6 percent, MCV 95.8 fL, MCH 29.6 pg/cell, and MCHC 30.9 g/dL, and the analyzer flagged the Hgb as abnormal because the MCHC was low. Read answer.
Q. We perform a cell count and differential for bronchoalveolar lavages. I understand the importance of a differential cell count, but is a cell count clinically significant when the bronchoalveolar volume is not standardized? Read answer.

May 2023—In 2020, when much of the world was locked down due to the pandemic, researchers at the University of Texas Medical Branch, in Galveston, began helping pharmaceutical companies evaluate the effectiveness of COVID-19 vaccines using a neutralizing antibody assay they had developed. A hot minute later (or so it seemed), some UTMB pathologists concluded that their patients might want to know if they had neutralizing SARS-CoV-2 antibodies.

 

Put It on the Board

May 2023—Kaiser Foundation Hospitals and Geisinger Health announced the launch of Risant Health and a definitive agreement to make Geisinger the first health system to join Risant Health to expand access to value-based care in more communities across the country. Upon regulatory approval, Geisinger becomes part of the new organization through acquisition.

Letters

May 2023—As members of the CAP Transfusion, Apheresis, and Cellular Therapy Committee, we wish to offer comments to the readers of CAP TODAY in response to the article, “Case review reveals latest on overtransfusion” (March 2023). The article reported on a single publication of retrospective reviews of transfusions given in 2012–2018 in 15 community hospitals (Jadwin DF, et al. Jt Comm J Qual Patient Saf. 2023;49[1]:42–52), based on approximately 100 encounters with transfusions per institution. The retrospective character of this work as well as its applied methodology raise several important questions regarding the true value of any conclusions and their generalizability. Interpretation of the presented data requires a thorough and unbiased discussion, as some numbers are significantly out of observed ranges elsewhere. For example, by the authors’ methodology, less than 10 percent of encounters had fully appropriate RBC transfusions.

 

Growing pains put gene panels in a pinch

April 2023—After years of excitement and scientific breakthroughs, the use of molecular testing to guide cancer therapeutics finally is coming into its own. Unfortunately, it appears to have landed in the wrong place at the right time. That place is a lonely spot, surrounded by gaps in economics and coverage, as well as knowledge, guidelines, ordering patterns, turnaround times, reporting, and the like. So plentiful are the gaps that, put together, they could form a vast, inhospitable space, a veritable Colorado Plateau, with molecular testing as a majestic, enticing but remote rocky pinnacle in the middle. Think Monument Valley. It’s worth the trek. The evidence in support of genomic profiling continues to grow. Simply put, “Patients with the right markers who get the right drugs do better,” says Neal Lindeman, MD, vice chair, laboratory medicine and molecular pathology, Department of Pathology and Laboratory Medicine, Weill Cornell Medicine/New York Presbyterian Hospital. But as numerous studies are showing, the lag in testing is growing as well.

Sorting out celiac disease with serologic testing

April 2023—Celiac disease incidence is up and the diagnostic rate is low, and it can be years from onset of symptoms to diagnosis. “It’s a long diagnostic odyssey, and so in the laboratory business, we’re all in to help,” says Annette Taylor, MS, PhD, associate vice president at Labcorp where she is strategic director of pharmacogenomics and scientific director of molecular genetics.

After negative CT for brain injury, a biomarker gap

April 2023—Traumatic brain injury triage in the emergency department is badly in need of biomarkers—and ones that can change practice. “If biomarkers don’t change practice, they’re a waste of time,” said W. Frank Peacock IV, MD, professor of emergency medicine, vice chair of research, and research director, Department of Emergency Medicine, Baylor College of Medicine.

Traumatic brain injury biomarkers

April 2023—Pradip Datta, PhD, D(ABCC), senior staff technical team leader, Siemens Healthineers, Newark, Del., highlighted the list of traumatic brain injury biomarkers—what they are, what’s available, what’s promising.

Lab leaders on hires, wages, scanners, and storage

April 2023—How is the demand for biomarker tests linked to new oncology drugs playing out in your health system? It is one of several questions laboratory leaders answered in a March 7 Compass Group call led by Stan Schofield, VP and managing principal of the Compass Group and formerly of NorDx/MaineHealth. That and digital pathology and the cost of storage, staffing and wages, the release of results, and the financial implications of the end of the public health emergency were the topics of the day. The Compass Group is an organization of not-for-profit IDN system laboratory leaders who collaborate to identify and share best practices and strategies.

Ancillary tests in gynecologic pathology—what and why

April 2023—With serous ovarian carcinomas and other gynecologic tumors, it’s molecular testing that increasingly sets the treatment course. “As pathologists, it’s exciting to us,” said Sadia Sayeed, MD, speaking at CAP22. “We’re learning that the immunostains we’re interpreting have greater implications than we ever thought they could.”
