Available assays

pipetteWhile the Endocrine BioServices laboratory is equipped and staffed to handle nearly any enzyme immunoassay (EIA) or radio immunoassay (RIA), we keep a regular stock of antibodies and conjugates for a number of commonly investigated hormones. This allows us to perform a wide range of assays for much lower prices compared to EIA or RIA kits from a commercial supplier, often pennies on the dollar.

If you do not see the hormone you wish to analyze, in nearly all cases we are able to order antibodies, conjugates, and other necessary supplies. We commonly order kits from MP Biomedicals and Cayman Chemical for EIAs and RIAs for which we do not keep a regular stock of antibodies and conjugates. In most cases, only the kits containing the antibodies, conjugates, and hormone standards are needed. We keep a regular stock of a variety of test tubes, solvents, pipettes, etc. (For a complete list of available equipment, click here). Please contact us for more information.



Hormone/Substrate Sample Medium Assay Type Note
Cortisol Blood, saliva, urine, feces EIA Medium may require enzyme hydrolysis and/or solvent extraction
Corticosterone Blood, saliva, urine, feces EIA Medium may require enzyme hydrolysis and/or solvent extraction
Progesterone Blood, saliva, urine, feces EIA Medium may require enzyme hydrolysis and/or solvent extraction
Pregnanediol-3α-glucuronide (PdG; primary progesterone metabolite) Blood, saliva, urine, feces EIA Fecal samples require enzyme hydrolysis and/or solvent extraction
Testosterone Blood, saliva, urine, feces EIA Fecal and urine samples require enzyme hydrolysis and/or solvent extraction
E2 (Estradiol metabolite) Blood, saliva, urine, feces EIA Medium may require enzyme hydrolysis and/or solvent extraction
E1C (Estrone conjugate) Blood, saliva, urine, feces EIA Medium may require enzyme hydrolysis and/or solvent extraction
Interleukin 1 beta (IL-1B) Saliva EIA Must record saliva flow rate when collecting sample
C-Reactive Protein Saliva EIA Passive drool is best method of sample collection
Secretory Immunoglobulin-A (SIgA) Saliva EIA Flow rate required; passive drool recommended; location dependent
Creatinine Blood, urine Modified Jaffe-endpoint Creatinine is a muscle metabolite that is commonly used to adjust hormone concentrations for the amount of fluid intake by an animal and solute concentrations in a given sample.
Corticosterone Blood, saliva, urine, feces RIA Primarily performed with feces and blood in our lab. Fecal samples usually require enzyme hydrolysis and solvent extraction.
Androstenedione Blood, saliva, urine, feces RIA Performed on urine and fecal samples, though commonly used on blood samples. Fecal and urine samples require enzyme hydrolysis and solvent extraction.
