The Artery is your community for finding solutions to your day-to-day clinical chemistry questions. Last month, several answers were found to questions ranging from "Has your institution seen a decline in prenatal screening? " to “Is it acceptable to dilute a quality control sample if it falls over the analytical measurement range?". Read on for the most discussed on the Artery in November.
Screening Test Decline – What Now?
One laboratory’s volume of prenatal screening has significantly declined within the past 2 years. With concern over maintaining medians, new approaches must be considered for screening tests. Has your institution seen this same decline? If so, how have you dealt with the issue?
The Validation Process
For routine clinical chemistry tests, does your laboratory validate assays for both serum and plasma or only for your primary specimen type? Arterians discuss different methods of validation across their labs. How does your lab handle validation of multiple specimen types?
To Dilute or Not to Dilute
Is it acceptable to dilute a quality control sample if it falls over the analytical measurement range? One laboratorian reaches out for advice on using dilution rather than purchasing a new sample. What would your lab do in this situation?
