Saliva is the fluid that keeps our mouths moist which aids in our eating process, helps us to speak, keeps our teeth and gums healthy and health. Saliva is secreted by the salivary glands, filled with proteins and very minute amounts of biochemical that flow in to the mouth from the blood serum. This is why illnesses, DNA and drugs can be detected via our saliva.

The compounds produced by these conditions, our DNA and taking drugs travel with the blood serum and over time build up enough to be found in the saliva. Saliva is a relatively new way of testing for diseases, drugs and DNA in comparison to blood and urine tests. Saliva was used for minor medical testing intermittently much earlier however, saliva tests were developed gradually after a discovery in the late 60s that saliva acted similarly to hormonal changes in cervical mucus that indicated when a woman would ovulate. This led to a saliva test for ovulation and the rest is history!

Saliva testing is now available to identify many different markers for conditions, DNA and drugs. Saliva tests can test for problems in the endocrine system, inflammatory conditions and infections. These tests can diagnose diseases like HIV, cancer, allergies with a piece of cotton swab or a simple swab from the cheeks with a cotton tip! Swab testing is also growing in favor as it is safe, non-invasive, affordable, accurate and easy to collect.

Children, pets and people with an aversion to needles are more comfortable with a saliva test and saliva can be taken multiple times without discomfort or problems, for monitoring of illnesses that needs to be regular. Some saliva tests available today are:-

  • HIV test
  • Hormone Levels
  • Adrenals
  • Drugs
  • DNA
  • Fertility
  • Heart Diabetes
  • Various cancers

The Saliva Test at Home:-

Saliva testing for nutrition is being researched now and like blood and other testing techniques will be able to detect more deficiencies and levels of health. Saliva is more commonly becoming used as a diagnostic fluid. The faster turnaround and lower costs to perform these tests allows patients to have earlier treatment and less visits to the clinic. Where we used to have to go to the hospital or the doctors for blood samples or lengthy tests, we can now even take a saliva test in the comfort of our own home with highly accurate results.

Salivary testing has already been used by the U.S. government to monitor astronauts' circadian rhythm shifts before a flight and to test the hormonal profiles of soldiers in military survival training. Other major advances in saliva testing are also on the horizon with possible lab-on-a-chip technology allowing the tiny device to sit on a person’s tooth and monitoring medication levels and lifesaving detection of biomarkers for specific disease states such as blood sugar levels in diabetes sufferers.

With advances like these in the landscape of saliva testing ever changing who knows what amazing test will be produced next using the humble spit.

Saliva Test

Saliva testing is becoming more popular as advances are made to cover more conditions that can be tested for. Saliva is easy to use for testing as it is easy to obtain, many samples can be taken at one time and saliva can be continuously tested over longer periods of time for conditions that need to be monitored. Saliva also has the ability to be frozen and the leftover specimen used at a later date. Less collection devices are also needed which helps lessen the possibility of contamination. It is a pain free method so is also preferred when taking a sample from a child or a person with an aversion to needles or someone who has trouble urinating.
