Please refer to the Endocrine Appendix of the LabCorp Directory of Services for instructions on multiple specimen testing.

This panel is a series panel requiring multiple tubes to be drawn at multiple time points. This panel is used to collect an initial tube (baseline) and then treat the patient with a drug (pill or shot) or other treatment (such as glucola) and then collect more tubes after the dose. If you are not giving the patient a pill or shot or other treatment after the first sample draw, do not use this panel. This series should not be collected until the clinician is contacted to determine why a series is ordered.
