For all species

Collect either serum or plasma. Send serum or plasma only, in a clean, labeled vial. Serum separator tubes are NOT recommended.

A volume of 2 mL of plasma or serum is sufficient for most assays. FSH and LH require at least 3 mL.

Sera or plasma should be harvested as soon as possible. Hemolysis should be minimal. If you cannot separate the serum from red cells, you should ship it as quickly as possible using a cold pack to prevent hemolysis. Ice packs are NOT necessary when sending serum or plasma samples, except for ACTH test.

Please include completed Hormone Assay Request Form. Please, put up to five samples per form when submitting multiple samples in the same shipment. We will contact you by fax or phone with the results as they are completed. Most assays are completed the day we receive the sample.

If you are sending samples from a foreign country please include our Import Permit.

To send your samples from outside of the U.S. please follow these steps:

1. Collect serum or plasma. Harvest serum or plasma from the red blood cells within 12 hours. Hormone concentrations are stable for up to 4 days at room temperature. Send only serum or plasma ; no red cells!

2. A volume of 2 mL of serum or plasma is required. For each additional assay on the same sample send an additional 1 mL of serum or plasma.

3. FSH & LH require at least 3 mL of serum or plasma.

4. Complete International International Hormone Assay Request Form [MS/DOC]; [.PDF file] (click the appropriate file type to download)

Performed in BATCHES (held until a critical number of samples is reached):

~ LH
 (EDTA Plasma required, FROZEN in PLASTIC vial, sent OVERNIGHT on ice. If other tests requested as well, a separate sample is needed for ACTH.)

Cultures are performed with an average turn around time of three days. Those with fungal growth will require approximately four days to complete. All isolates are screened for sensitivity against the following antibiotics:
