Q&A column

Q&A column

NOVEMBER 2024 Q. Our laboratory was cited for a deficiency because the manufacturer and methodology of our tumor marker assay was not available to clinicians. What is the reasoning behind this requirement? Read answer.
Q. For patients who have a hematocrit level greater than 55 percent, is it okay to use a CBC (hematocrit) that was not collected at the same time as the citrate sample? For example, can we use a CBC collected within 24 hours for an inpatient and a CBC from a previous visit for an outpatient? Read answer.

Q&A column

October 2024
Q. Immunofluorescence microscopy results for antinuclear antibodies (ANAs) are reported as a titer. How can we best comply with CAP checklist requirement IMM.34120 Daily QC—Nonwaived Tests for ANA testing? Read answer.
Q. Is there a standard of care for anatomic pathology reporting? The CAP document “How to Read Your Pathology Report” states that pathologists “always perform the microscopic evaluation of a specimen, even if the final pathology report does not include a written description.” Must the testing pathology laboratory provide the patient with the microscopic description if it is requested and not included in the pathology report? Read answer.

Q&A column

September 2024
Q. When performing body fluid cell counts, we report total nucleated cells and RBCs. What cell categories should we report on the corresponding differential? Can we group together monocytes, macrophages, and mesothelial cells since it is difficult to distinguish reactive mesothelial cells from monocytes and macrophages? If so, what category name should be applied? Should we report mesothelial cells as a comment or include them in the differential? Read answer.
Q. Are nonlaboratory personnel who perform point-of-care testing required to be tested for visual color discrimination? Or is it sufficient that personnel pass a functional assessment during their competency evaluation to evaluate their ability to provide an accurate result on tests that require interpreting colors? Read answer.

Q&A column

August 2024
Q. I have been tasked with doing a quality assurance review comparing automated differential results to the manual differential done on the same patient. Do you have recommendations regarding acceptable analytical criteria? Read answer.
Q. Can activated clotting time results handwritten by a perfusionist be sent to the laboratory to be entered into the laboratory information system? Read answer.

Q&A column

July 2024
Q. Insulin assays traditionally have been used to work up hypoglycemia, but we are noticing more and more requests for insulin and C-peptide testing. Is there a reason for this shift? Read answer.
Q. How should a lot-to-lot formalin comparison be done? Read answer.

Q&A column

June 2024
Q. What are the requirements for correcting an automated white blood cell (WBC) count for the presence of megakaryocytes? Is there a formula for correcting it for megakaryocytes, as there is for the presence of nucleated red blood cells (nRBCs)? Read answer.
Q. Are there guidelines on how often a patient should be monitored for a blood transfusion reaction? Should reactions be monitored as frequently as vital signs? Read answer.

Q&A column

May 2024
Q. I know that CLIA is changing and more tests/analytes will become CMS regulated, along with other changes. Can you provide some background and an overview of the changes and when they will become effective? Read answer.

Q&A column

April 2024
Q. Ordering clinicians are requesting that our laboratory flag abnormally high absolute neutrophil counts (ANC) on peritoneal fluids. We cannot find sources for reference ranges, but there is literature that states that a polymorphonuclear cell count greater than 250/μL is a reliable discriminatory test for bacterial peritonitis. We would like to use this as our reference and flag results with an ANC greater than 250 cells/μL as abnormally high. Is this acceptable? Read answer.

Q. How do you code fallopian tubes submitted for sterilization with a finding of a paratubal cyst? Read answer.

Q&A column

March 2024
Q. Is it a requirement that routine bacteriology cultures (for example, urine, sputum) be plated in a biological safety cabinet in your typical hospital biosafety level 2 laboratory? Is it safe to read these cultures on an open bench? Read answer.

Q. What source should a laboratory use for reference intervals for analytes? Read answer.

Q&A column

Feburary 2024
Q. In a case of suspected drug-related death, how specific can an autopsy be in identifying the drug(s) that might have caused the person’s death and the amount of drugs present? For example, can a toxicology report say a person’s death was caused by a fake oxycodone pill containing fentanyl? Read answer.

Q. A nephrology patient who has been treated with vitamin D2 for several years contacted our laboratory to find out why their 25-hydroxyvitamin D level of 60 ng/mL is now considered elevated when before it was within the normal range. How can we explain this? Read answer.
