About Saliva Testing
Saliva testing has many advantages over blood testing. Saliva specimen
collection does not require a blood draw and there are no risks to
patients. Saliva collections are convenient and can be done at work or
at home. When stored properly, saliva samples are stable for several weeks.
With an accuracy of 92-96%, saliva testing is more accurate than blood
testing. The ability to collect more than one specimen is another
advantage of saliva testing because this can give providers more
information than a single collection. Compared to blood testing, saliva
testing is also more affordable.
The method of testing saliva that Diagnos-Techs, Inc. uses is called
ELISA testing. For more in-depth information about this kind of testing
Why Saliva?/Saliva Testing at a Glance
There are several different ways of measuring the hormones in a person’s
body. Most blood and serum tests look only at the level of hormones that
are present in a person’s tissues. This is known as “bound hormone
Saliva testing looks at the “unbound hormone levels” also known as “free
fraction hormone levels” which are the hormone levels that are
available to be used by the body’s tissues. This gives providers a
better idea of the levels of hormones that are actually influencing the
tissues, rather than just the level of hormones that are present in the tissues.
Measuring free fraction hormone levels gives a provider more information
than measuring bound hormone levels. Usually, when bound hormone levels
are measured, a provider needs to guess at the level of hormones
affecting the tissues. This is not the case when measuring free fraction hormone levels.
The accuracy of saliva testing, together with its affordability, convenience, and the ability
to collect multiple specimens makes saliva testing superior to blood testing.
