Why is recognizing normal versus abnormal laboratory values important?

• A. To determine patient height
• B. To evaluate collection success and processing criteria
• C. To schedule follow-up visits
• D. To choose a different test

Answer: (B)

Recognizing normal versus abnormal lab values helps determine whether a result is trustworthy by showing whether the specimen was collected and handled correctly. If the result sits in the expected range, it supports proper collection and processing. When values are outside the reference range, you consider whether that reflects the patient’s biology or a preanalytic issue, such as a hemolyzed sample that falsely elevates potassium, a delayed processing that lowers glucose, or improper storage that alters several measures. This mindset prevents misinterpretation and informs whether a repeat test or adjustments to collection/processing are needed.
