November 2025—A study of four laboratories’ experiences with subclassifying variants of uncertain significance (VUS) found that variants were more likely to be reclassified as benign than pathogenic. The VUS-high subclass had the highest percentage of reclassifications, but represented a smaller proportion of total VUS classifications.

Q. Clinicians at my hospital doubt my prolactin results. They report patients with prominent pituitary adenomas who have normal prolactin results. There are other patients who have hyperprolactinemia but no adenoma or galactorrhea. In those patients, the prolactin concentrations remain elevated even after therapy. Can you clarify? Read answer.
Q. Is it necessary for a lab to report a corrected sodium level when the glucose level is really high? Studies show pseudohyponatremia can occur due to hyperglycemia. How common is this, and how do we decide which correction factor to use? Is it possible that this is easily overlooked by providers due to comorbidities in patients? Some references say there is a need to correct glucose for each 100 mg/dL increase above 400 mg/dL. Read answer.
November 2025—UpToDate, a widely used clinical decision support tool, is facing competition from OpenEvidence, an AI-powered tool that provides more accurate and context-specific answers to complex clinical cases. While UpToDate is adding its own AI capabilities, the optimal source of truth for AI-driven clinical decision support remains uncertain.
November 2025—The FDA cleared Roche’s Elecsys pTau181 test, a blood-based biomarker for Alzheimer’s disease assessment in patients 55 and older. The CAP requested an exception for physician J-1 visa holders, concerned the proposed four-year visa limit could hinder international medical graduates pursuing pathology careers. The Association for Molecular Pathology and CAP published a consensus recommendation for a simplified next-generation sequencing molecular biomarker report template.
October 2025—For my inaugural column in CAP TODAY, I’d like to begin by saying thank you. Thank you, CAP members, for the honor of allowing me to serve as your president. Thanks to my mentors, peers, and colleagues for helping me along this path. And my deepest gratitude to my wife, Jenny, and my daughter, Jasmine, for the extraordinary journey that began in China and led to my own American dream in the U.S. and to Louisiana, where I practice.
October 2025—Whole genome sequencing is being evaluated in newborn screening to increase the diagnosis and treatment of rare clinical conditions. Such screening raises ethical questions about which results to report and the impact of those results on parents and their children. It is important to focus on societal norms when designing whole genome sequencing–newborn screening (WGS-NBS) to make sure people accept the testing and minimize patient harm. Although parents value the fact that WGS-NBS can lead to early diagnosis and treatment of various conditions, they recognize that results may cause psychological distress, eliminate children’s autonomy, raise data-storage and privacy concerns, and lead to uncertainty regarding adult-onset medical conditions. The public, in general, supports WGS-NBS for clinically actionable childhood-onset conditions, with the caveats that health professionals are trained to interpret such results and genetic counseling is available.
October 2025—Crystal-storing histiocytosis is a rare disorder in which crystals accumulate in the cytoplasm of histiocytes. It is usually associated with a lymphoplasmacytic neoplasm. Cutaneous crystal-storing histiocytosis (CSH) is extraordinarily rare and limited to case reports in the literature. The authors reported on two cases of CSH with cutaneous involvement. Case one was a 65-year-old male with a four-month history of a pruritic eruption that started as a solitary pink to skin-colored indurated plaque on the anterior neck before progressing to involve the whole neck, chest wall, and face.
October 2025—GATA2 deficiency is a rare inherited condition that disrupts the normal development of blood and immune cells. People born with this genetic disorder may experience low blood counts, frequent infections, or such problems as lymphedema and hearing loss. The most serious long-term risk is development of myelodysplastic syndrome (MDS), a bone marrow disorder that can progress to leukemia. The authors conducted a large study in which they followed 218 people with confirmed GATA2 mutations to understand when and how MDS develops. In this cohort, symptoms of GATA2 deficiency were present in 205 of the participants, of whom 187 (91.2 percent) had MDS.
October 2025—Large language models are becoming commonplace for personal and business use. The health care community is leveraging large language models (LLMs) for various purposes. Researchers at the University Medical Center Hamburg-Eppendorf, Hamburg, Germany, have successfully used open-source LLMs to extract critical medical data from pathology reports. They conducted a study that demonstrated how LLMs can transform unstructured clinical text into structured pathology data. While pathology reports are rich in information about tumor type, size, and stage, their narrative format makes automated data extraction difficult.

Q. Is telepathology used much in the United States for histology interpretation and diagnosis? For example, is it used to interpret digitally transmitted histology slides when working from home? Read answer.
Q. When a patient has a hematocrit level of ≥ 55 percent and a normal PT and APTT, do you still correct sodium citrate and ask for a redraw? Is it crucial to ask for a redraw when the emergency department orders a stat PT and APTT? Read answer.
