Q&A column

May 2026
Q. When we receive new immunohistochemistry antibodies or DAB kits, they undergo a quality control process. Every institution where I have worked has done this task a little differently. When a laboratory receives a new antibody, what is the correct QC process? What if we receive two units of the same antibody from the same lot but one came in on Thursday and one on Friday? Read answer.

Q&A column

March 2026
Q. How should a blood bank respond when a non-irradiated blood product is inadvertently transfused to a patient who requires irradiated components, and what steps must be taken to ensure patient safety and regulatory compliance? Read answer.

Q. We are using direct smears for nongynecologic fine-needle aspirations and thinking about switching to liquid-based cytology (SurePath) preparation. There is nothing in the CAP accreditation checklist that pertains to a switch in slide preparation method… Read answer.

Q&A column

Q. Why aren’t more medical students interested in applying for a pathology residency? Read answer.

Q. What is your opinion on employing qualitative rapid homogeneous immunoassay (enzyme-multiplied immunoassay technique, ELISA) urine screens for tricyclic antidepressant (TCA) testing in pregnant women and emergencies involving neonates, particularly at a low cutoff threshold of 300 ng/mL? Read answer.

Q&A column

Q. Now that the CMS allows direct observation for competency assessment to be performed virtually, does the CAP also allow it? If so, can you provide guidance? Read answer.

Q. We have implemented quality control at 10x in accordance with the Westgard rules. I use three levels of QC. If the results of two levels of QC are moving properly above and below the mean and only one level is showing a trend of a 10x rule violation, what corrective action should I take? Read answer.

Q&A column

November 2025
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.

Q&A column

October 2025
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.
