Lumipulse G β-Amyloid Ratio test has breakthrough device designation
March 2019—Fujirebio Diagnostics received on Feb. 1 breakthrough device designation from the FDA Center for Devices and Radiological Health for its Lumipulse G β-Amyloid Ratio (1-42/1-40) quantitative in vitro diagnostic test. The test uses measurable β-amyloid 1-42 and β-amyloid 1-40 concentrations found in human cerebral spinal fluid and combines those concentrations into a numerical ratio of β-amyloid 1-42/β-amyloid 1-40 to estimate the presence of β-amyloid neuritic plaque pathology in the brain. The Lumipulse G β-Amyloid Ratio (1-42/1-40) combines the results of Lumipulse G β-amyloid 1-42 and β-amyloid 1-40 using the Lumipulse G System. The ratio results are intended to aid in assessing adult patients, ages 50 and over, who present with cognitive impairment and are being evaluated for Alzheimer’s disease and other causes of cognitive decline. The results must be interpreted in conjunction with other diagnostic tools such as neurological examination.

Building a lab or modernizing? Don’t forget the following
March 2019—Building a new pathology lab or revamping an existing one gives laboratory decision-makers an opportunity to rethink information technology infrastructure and address persistent problems, plan for new technology, and improve processes.

From the President’s Desk: Our study of member services and support

March 2019—We launched the CAP member services and support strategy two years ago, setting out to figure out which benefits were most valued by the greatest number of members, identify places where we could find better ways to direct or maintain them, and see where we could be falling short. To keep everyone connected and everything on track, we created a coordinating group whose members had access to a fine staff and thoughtfully curated findings from years of member surveys and market research. Our own surveys showed how the interests and needs of our members overlapped. The market provided context.

March 2019—Evaluation of ethanol interference on routine biochemical tests: Ethanol, a central nervous system depressant widely consumed in many societies, is metabolized in the liver through multiple enzymatic pathways. If the liver’s capacity is exceeded, the excess alcohol will flood into the systemic circulation.

March 2019—ALK expression in angiomatoid fibrous histiocytoma: a potential diagnostic pitfall:
The authors recently encountered a case of primary pulmonary angiomatoid fibrous histiocytoma (AFH), which was initially misdiagnosed as inflammatory myofibroblastic tumor based in part on anaplastic lymphoma kinase expression by IHC. Prompted by this experience, they evaluated anaplastic lymphoma kinase (ALK) expression in 11 AFH, 15 inflammatory myofibroblastic tumors (IMT), and 11 follicular dendritic cell sarcomas using three antibody clones: D5F3, 5A4, and ALK1.

Molecular pathology selected abstracts

March 2019—Using circulating cell-free fetal DNA to test for monogenic disorders: Screening for fetal chromosomal abnormalities can be performed by noninvasive methods in which fetal cell-free DNA (cfDNA) circulating in the maternal blood is isolated and analyzed. However, the standard of care for screening for monogenic diseases remains population-based carrier screening—testing the parents for their carrier status of deleterious genes.

Hologic assay is first FDA-cleared test to detect M. genitalium
February 2019—The Food and Drug Administration granted clearance for Hologic’s Aptima Mycoplasma genitalium assay. This is the first test the FDA has authorized for M. genitalium detection. The FDA reviewed data from a clinical study that included testing of 11,774 samples. The FDA says the study showed that the Aptima assay correctly identified M. genitalium in approximately 90 percent of vaginal, male urethral, male urine, and penile samples. It correctly identified M. genitalium in female urine and endocervical samples 77.8 percent of the time and 81.5 percent of the time, respectively. Vaginal swabs are the preferred sample type owing to better clinical performance. Alternative sample types, such as urine, can be used if vaginal swabs are not available. In addition, the study showed that the test correctly identified samples that did not have M. genitalium present 97.8 to 99.6 percent of the time. The FDA reviewed the Aptima M. genitalium assay through the de novo premarket pathway.

Q&A column

Q. When performing a manual differential that contains immature cells, such as metamyelocytes and myelocytes, do you report an absolute count on all of the individual cells in the myelocytic line, or do you group them together and calculate one ANC? What about lymphocytes and reactive lymphocytes? Read answer.
Q. Why and in what employment screening settings is the two-step skin test for Mycobacterium tuberculosis recommended? Read answer.

From the President’s Desk: Giving group practices what they need most

February 2019—In last month’s column, we talked about practice engagement as an umbrella term for laboratory medical direction and practice management that builds strong relationships within and beyond the laboratory. The CAP Practice Management Committee has been taking the lead on this, but it cuts across multiple domains; the conundrum, as always, is the complexity of what we do. Practice management tools designed for other settings cannot meet our needs because we must address economy, efficiency, effectiveness, and collegiality concerns specific to pathology. But then, affinity for complexity is how we landed here in the first place, so that plays to our strengths.
