September 2026—HIV remains a major global public health concern, with an estimated 40.8 million people living with the virus in 2024. The challenge is particularly striking in low- and middle-income countries, where access to diagnostic testing may be limited. The World Health Organization’s universal test-and-treat strategy recommends that patients diagnosed with HIV immediately begin antiretroviral therapy regardless of their CD4 cell count or clinical stage. This strategy has placed greater emphasis on routine viral load monitoring, leading to a marked decline in CD4 testing and the discontinuation of many point-of-care CD4 platforms.

Q. What is the percent acceptability when conducting a comparison test of activated clotting times (ACT)? Read answer.
Q. Is there any circumstance in which a manual bone marrow differential would be more accurate than flow cytometric analysis? Read answer.

September 2026—Twelve U.S. health systems have joined forces with the clinical artificial intelligence company Aidoc to form the Diagnostic AI Consortium, with the goal of harnessing AI to improve the safety, quality, and speed of patient diagnosis and developing and adhering to standards for evaluating and governing the capability.

Put It on the Board

September 2026—A federal appeals court struck down portions of the federal regulations governing the calculation of the qualifying payment amount (QPA) under the No Surprises Act. The U.S. Court of Appeals for the Fifth Circuit, sitting en banc, issued its decision Aug. 11 in Texas Medical Association v. United States Department of Health and Human Services. The QPA is an insurer-calculated figure that is an important element in independent dispute resolution proceedings in which the amount an insurer owes to an out-of-network provider is adjudicated.

Clues, questions in HR deficiency testing

August 2026—Testing for homologous recombination deficiency (HRD) is not for the faint of heart. Even the experts agree. Tricia Numan, MD, says that when she first became involved in the topic, “I didn’t realize how many components went into HRD testing,” including germline alterations, somatic alterations, and various classifications of genomic instability.

Eyes on new tick-borne disease diagnostics

August 2026—In a summer of more ticks, more diseases, and more tick species expanding to new areas and bringing diseases with them, what Bobbi Pritt, MD, MSc, would like to see are more—and better—diagnostics in early Lyme disease. Laboratory scientists are inching toward improved solutions, though nothing is commercially available now. “I’m cautiously optimistic. I wouldn’t say I’m excited yet,” says Dr. Pritt, co-director of vector-borne diseases laboratory services and chair of the Division of Clinical Microbiology at Mayo Clinic in Rochester.

Urothelial carcinoma: histologic subtypes and divergent differentiation

August 2026—Recognizing and reporting histologic subtypes and divergent differentiation in urothelial carcinoma is critical for diagnosis, prognosis, and treatment. “Ideally, you want to mention the subtype histologies in pathology reports and quantify the amount,” said Francesca Khani, MD, associate professor in the Department of Pathology and Laboratory Medicine and in the Department of Urology, Weill Cornell Medicine. In a CAP25 session last fall, Dr. Khani spoke of the mimics of benign entities and of other malignancies.

Views on AI use for lab test orders and reports

August 2026—Would artificial intelligence as an aid in ordering laboratory tests and making reports understandable to patients be a worry or a welcome step? In a June 2 online roundtable led by CAP TODAY publisher Bob McGonnagle, a Compass Group member shared what he learned about an Epic pilot, and that launched the following conversation about the clinical laboratory and pathology reports that could be made easier for patients to understand. One participant’s view: “proceed with caution.”

Student-led workshops introduce pathology to peers

August 2026—A series of hands-on or role-playing workshops created by pathology student interest group leaders at a California medical school introduced pathology to dozens of students who would have otherwise completed their curriculum without that exposure.

AMP case report: Therapy-related acute myeloid leukemia in a patient with BRCA1-positive breast cancer and a DDX41 possibly germline variant

August 2026—The 2022 World Health Organization and International Consensus Classification frameworks recognize several well-defined myeloid neoplasm categories that arise in the setting of inherited genetic predisposition. These entities are grouped according to associated clinical features and include myeloid neoplasms with germline predisposition in the absence of antecedent platelet abnormalities or organ dysfunction (e.g. CEBPA, DDX41, and TP53), those associated with inherited platelet disorders (e.g. RUNX1, ANKRD26, and ETV6), and disorders linked to underlying or potential organ dysfunction.
