At POC and in lab, 2 new checks on SARS-CoV-2 testing

November 2020—The CAP released in September its proficiency testing program for SARS-CoV-2 antigen testing, with the first shipment to laboratories set for Nov. 30. It also introduced recently a Quality Cross Check program that makes it possible for labs performing nucleic acid amplification testing for SARS-CoV-2 to monitor performance across multiple instruments, in compliance with the CMS directive prohibiting proficiency testing on multiple instruments.

Cytopathology in focus: Gynecologic cytology PT appeals: where they started,where they stand

May 2020—The CAP implemented proficiency testing for cervical cytology in 2006 as mandated by federal legislation. The performance of participants and granting of appeals on glass slides in the first year of the CAP Pap PT program was reported in detail by Crothers, et al. Once a participant initiates an appeal, the slide in question is pulled from the program for a blinded review by three board-certified anatomic pathologists who are members of the CAP Cytopathology Committee. In the first year, 155 participants failed the PT examination and appealed their testing results on 86 individual slides. After review, appeals were granted for 21 slides, resulting in 45 exam failure reversals. The overall appeal rate was 13/1,000 slides in the program.

DIY or Survey? Identifying interfering substances

October 2017—The interfering substance: Whether it’s in-laws on your doorstep or lipemia in your specimen, it has to be addressed. Ask Michelle K. Zimmerman, MD. These days, Dr. Zimmerman uses the CAP Interfering Substance Survey to detect the presence of hemolysis, lipemia, and icterus in clinical chemistry samples at Indiana University School of Medicine, where she is an assistant professor of pathology and laboratory medicine. But before her laboratory started using the Survey, how did it handle those interferences?

Glucose PT criteria reset stirs standards debate

June 2016—It may not be an exact science, but resetting standards is a long-established means of improving quality of testing, and it can also be a way of adapting to improvements in quality that have already been realized. In the case of the CAP’s recent tightening of proficiency testing criteria for hospital glucose testing, both purposes are at work.

3 new NGS Surveys on CAP 2016 PT launchpad

November 2015—More than two years ago, when the CAP decided to move forward with proficiency testing for next-generation sequencing, the decision point was modest. “We estimated that about 35 labs would subscribe, based on survey information, and that was sufficient for us to move forward,” says Karl V. Voelkerding, MD, chair of the CAP Next-Generation Sequencing project team.

NY cuts labs loose from requirement to use state’s PT

October 2015—With the New Year approaching, many laboratories that test New York state specimens can look forward to breathing a sigh of relief. Regulatory relief, that is. Thanks to a policy change by the state’s Clinical Laboratory Evaluation Program (CLEP), beginning Jan. 1, 2016, laboratories will still have to be inspected by the state, but can fill New York’s proficiency requirement with the proficiency tests of any organization to which the CMS has granted deemed status under CLIA.

PT referral rules bring regulatory relief for labs

July 2014—Laboratories now may be saved from draconian penalties, such as loss of a CLIA license and probation periods, for mistakenly sending proficiency test specimens to another facility. Under new rules published by the Centers for Medicare and Medicaid Services, laboratories have the regulatory relief the CAP advocated during the past decade. The CMS will still severely punish those attempting to cheat on proficiency testing, but laboratories that unknowingly or unintentionally refer PT specimens will face alternative sanctions, according to the regulations.
