One day means results are available 1 day after the sample is received in the laboratory.

30 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

45 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
