The use of matrices other than blood for endocrine assessment is a common necessity when working with species that are difficult to sample. Because hormones are often present in other tissues, matrices that are more easily collected in the field or from species where blood collection is difficult are often preferred. A reduction in the time to sampling or remote sampling have the added advantage of not inducing a measurable stress response, meaning that the sample collected is a baseline representation of that animal’s stress and reproductive profile. However, reliable measurement techniques must be developed to ensure accurate measurement using these matrices with poorly known matrix interferences. Therefore, NIST works with stakeholders to develop measurement techniques that allow for endocrine assessment using alternative matrices.
The monitoring of wildlife and broodstock health through endocrine assessments is critical to understanding reproduction and stress. However, collection of traditional blood samples can be difficult and the sampling process can alter the hormone profile. Therefore, NIST works with stakeholders to develop measurement techniques for the quantitation of hormones in non-traditional and less invasive matrices for the monitoring of wildlife health and reproductive yields of broodstock.
