In this episode you will learn: - Daily QC for POCT devices requires running two levels of controls: a low/normal and a high/abnormal. - Levey-Jennings charts are used to visually track QC data over time, helping to identify shifts and trends that indicate potential problems. - The Westgard 1-3s rule requires immediate rejection of a QC run if a result falls outside three standard deviations from the mean. - When a QC result is out-of-range, you must stop patient testing immediately and perform corrective action before rerunning the control. - Meticulous documentation of all QC results, out-of-range flags, and corrective actions is mandatory for regulatory inspections.

He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The fundamental difference: Plasma contains fibrinogen because clotting is prevented with an anticoagulant, while serum lacks fibrinogen because the blood has clotted. - Why plasma from an anticoagulated tube (e.g., green top) is essential for STAT tests to ensure a rapid turnaround time, avoiding the 30-60 minute wait for a serum sample to clot. - How to identify the correct tube for each sample type: Anticoagulant tubes like lavender, green, or light blue tops yield plasma, whereas tubes with clot activators or no additives, such as red or gold SSTs, yield serum. - That specific tests require a specific sample; for example, coagulation studies (PT/INR) must use plasma to measure clotting factors, while other chemistry tests may require serum to avoid anticoagulant interference. - A helpful mnemonic to remember the difference: "Plasma Prevents Clotting, Serum Settles After."

In this episode you will learn: - That light exposure causes photodegradation, which leads to falsely low test results for sensitive analytes. - The most common light-sensitive specimens you must know for the exam are bilirubin, vitamin A, vitamin B12, beta-carotene, and porphyrins. - The correct procedure for protecting a light-sensitive specimen is to use an amber-colored tube or to wrap the collection tube in aluminum foil immediately. - How exam questions may test this knowledge through direct identification or by presenting clinical scenarios involving erroneous results. - A common exam trap is confusing light protection with temperature requirements (chilled or warmed specimens) or forgetting that light exposure falsely lowers, not raises, the result.
