Choosing Salivary Analytes & DNA

Consider parameters that may effect your analyte of choice when collecting from specific participant groups, such as participant segments that may likely be supplementing hormones, taking medications, may be prone to oral injury or inflammation,  or participating in actions that may influences salivary analyte levels.

We do not track this information internally, however some published data differentiates their descriptive data by race.

Several researchers have tracked salivary hormones across the menstrual cycle.  These publications are easily found via pubmed.  In general, the levels of salivary hormones show the expected changes across cycle phases when the comparison is made within individuals.  There are considerable individual differences which make the comparison of levels by cycle phase between individuals less meaningful.

We have range values in the case of assay kits which have been 510k cleared by the FDA for Diagnostic use. These data are available in the specific kit inserts on-line.  With research use only kits a substantial amount of the published literature is based on Salimetrics assay kits.  It is likely that studies have been published that would provide ballpark information about expected ranges in the age groups of interest to your specific study. We also recommend that researchers establish a range of normal values for a healthy population within your specific study.

Species specific data can often be found in the scientific literature, but we do not track this information internally.

The literature is rather extensive on this subject for several salivary analytes.  In fact, this publication has performed a meta-analysis for expected diurnal salivary cortisol reference ranges;
