FAQsOrdering TestsPreparing Your Specimen

What is the minimum specimen volume for my specimen?

The minimum specimen volume for each specific specimen is available when you log in to MayoAccess as a client.

The Specimen Required section of each test (in the online Test Catalog or in MayoAccess) lists the preferred specimen volume - a volume that optimizes testing and allows the laboratory to quickly process specimen containers, present containers to instruments, perform the test, and repeat the test, if necessary. When venipuncture is technically difficult or the patient is at risk of complications from blood loss (for example: pediatric or intensive care patients), smaller volumes may be adequate.
