A member asked:
Is it possible that laboratory test result varies from one clinic to another?
8 doctors weighed in across 3 answers
Yes: Different labs some times use different methods that may provide different results on a given sample. Each lab reports its normal values and that should be noted in addition to the results of the sample. For tests that need longitudinal monitoring, e.g., tumor markers, it is better to use one lab.

Yes: Each laboratory has their own normal ranges for the tests they do. Also, even at the same lab, your numbers can vary because of time of day, diet and or other factors. Your doctor can interpret what the number means for you. The meaning of test results varies from person to person.

Absolutely: Many of these variations occur because of differences in machine calibrations, laboratory parameters, and what is considered normal for that laboratory.
