 This issue is currently being addressed through identification of multiple biomarkers that are correlative of a disease; these can then be screened concomitantly to create a comprehensive panel of tests that significantly increases diagnostic specificity.Of note, certain types of saliva testing are considered by many to be more specific than blood testing; this is particularly true for steroid hormones.Since salivary hormone tests measure only those hormones that are not bound to sex hormone-binding globulin (SHBG) or albumin, they are regarded as reflecting only the bioactive (“free”) fraction.
