Q. Can you explain further the revised CAP checklist requirement COM.40850 “LDT and Class I ASR Reporting,” which says to describe the method and performance characteristics in test reports unless the information is available to the clinician in an equivalent format? Read answer.
Q. Can we see reactive lymphocytes in the pediatric population (under age two), and can we report them? Read answer.
Q. Is anticoagulant adjustment in citrate tubes necessary when a patient’s hematocrit is less than 20 percent? Read answer.
Q. What is the substitute test for HbA1c for a patient with homozygous variant hemoglobin? Is a fructosamine and/or glycated albumin test appropriate? Read answer.
Q. How can one wisely apply GATA3 immunohistochemistry as a useful tumor marker in diagnostic surgical pathology? Read answer.
Q. Is there expert advice or standard practice for releasing preliminary critical values for patients to the LIS pending subsequent technologist or technician verification and documentation? Read answer.
Q. We hope to validate a procedure for the fixation, decalcification, and staining of bone marrow specimens but we will not be able to access fresh marrow specimens for our decalcification validation. Can you recommend an alternative tissue to validate the preservation of tissue morphology and antigenicity after decalcification? Read answer.
Q. What is the best way to report fecal fat testing? Read answer.
Q. Who developed the formula for the corrected white blood cell count for nucleated red blood cells, and how was the formula established? Read answer.
July 2018—Is CD30 currently being used as a predictive marker for therapy? Due to laboratory construction, our molecular instruments were relocated within the lab. Is full test validation required in this case? Or is running at least 20 known samples enough to verify the instrument/assay performance specifications?
June 2018—What is the role of total testosterone and free testosterone in gauging the effectiveness of androgen deprivation therapy?
We are planning to validate the mismatch repair panel in our immunohistochemistry laboratory. Do we use the CAP guidelines for antibody validation for a nonpredictive marker or a predictive marker?
May 2018—Our immunohistochemistry laboratory is moving to a new building across the street. We are not getting new equipment, just moving the machines to the new building. Do we need to perform a full revalidation of all our antibodies?
April 2018—A semen analysis for viability was collected at 9:30 AM and not received in the laboratory until 1:40 PM. Our standard operating procedure says this test must be analyzed one hour after collection, with no disclaimers stated for late receivables. Therefore, it is my understanding that a specimen received five hours after collection would be considered unacceptable because the viability of the semen is compromised and the collection delivery does not follow our SOP.
March 2018—Our pathology group has an unusual case of residual squamous cell carcinoma of the lung in a lobectomy specimen after chemotherapy. The lung shows a hilar scar (1.7 cm) involving the lung parenchyma and the peribronchial adipose tissue. In the scar there is residual carcinoma (0.4 cm) that focally is involving the peribronchiolar adipose tissue around the lobar bronchus. The focus is located at 0.3 cm of the final surgical resection margin of the bronchus. Because the tumor involves peribronchiolar adipose tissue, is it considered outside the lung (extension outside the lung)? Since the tumor is in the mediastinal fat around the bronchi and had to invade the viscera pleura to invade the peribronchial adipose tissue, would the tumor stage be ypT2a? Or T3 since it is invading part of the mediastinal fat? Or should it be pT1?
