Candida Saliva Test

Candida is still a mysterious illness that even medical practitioners don’t really know the exact cause of it. With the many different types of Candida infections, doctors many carry out a number of different types of tests. But one of the best ways to find out if they have Candida is to perform the Candida saliva test at home.

The Candida saliva test can help you understand how severely Candida growth has occurred within your system. The Candida saliva test can be performed at home with just a glass of water. It is suggested that after waking up in the morning (before brushing your teeth or drinking water), first take a glass of cold tap water and spit some saliva into it. After spitting the saliva into the glass of water, let it settle for around 10 mins. During this process you may see the following things happening in the glass:

  1. Strings hanging down the saliva

  2. Cloudy saliva settled at the bottom

  3. Suspended forms of saliva under the strings


These three signs are clear signs of Candida growth, but if the saliva remains at the top of the water without stringing down then there’s no Candida present.

If you see any “string” formation within the first few minutes of the process and then followed by thick saliva settled at the bottom, or if the whole saliva looks suspended near the bottom of the glass, then there is Candida overgrowth within your body. This indicates that you need some serious attention to fight the Candida growth in your body. Precautions and mild medication will be good to keep away Candida.

On the other side if the saliva floats on the water and the water is clear there is most likely no Candida overgrowth.

How Does Candida Saliva Test Work?

Candida is a kind of yeast fungi, and a concentration of it within the body can build up within the overnight saliva. So to get the most accurate result, the Candida saliva test has to be performed is the morning after you wake up. Candida is normally heavier than saliva and water, and thus tries to settle downwards, forming either string like legs or settling at the bottom. Sometimes slightly lighter saliva floats around like suspended particles. Now, depending on the amount of these formations, we can judge how systemic the infection is.

Candida is everywhere and is believed to be present in every human being. So the presence of little Candida doesn’t necessarily indicate a Candida infection. Candida is normally present in the mouth and gut of every healthy adult along with other bacteria. This Candida and bacteria colonize within the mouth during the night, which is basically responsible for morning breath. If a person is not affected by Candida overgrowth and they perform the Candida saliva test, he/she might see that their saliva mostly remains at the top. However, a person with a symptoms of a cold/flu may also see that their saliva has shrunk to the bottom of the glass, which they can just be bacteria cells clumped together, and not Candida. So it might be unwise to perform just the Candida saliva test and concluding that one has Candida overgrowth. Other tests should also be done such as blood test, stool analysis or urine test from the GP, to get a better understanding of Candida growth occurring within the body.


Studies supporting presence of Candida in Saliva and their Significance

A study published in ‘The Journal of Infectious Diseases’ was conducted to find the stimulation of Candida growth in saliva as a result of diabetes mellitus, or using antibiotics or corticosteroids, which in turn affects the amounts of glucose in saliva. This study clearly stated that patients that are undergoing therapy with antibiotics or corticosteroids or the ones suffering from diabetes mellitus have an increased amount of glucose in their saliva and this leads to presence of high Candida in the saliva. So the findings of this study suggest that having diabetes mellitus, or going through therapy with antibiotics or corticosteroids, can give a high reading of Candida within the spit test. Also, having these illnesses or methods of therapy may be one of the root causes as to why one may have developed a Candida infection in the first place.

The ‘Journal of Clinical Microbiology’ published a study that studied the relationship between the clinical status of a few human subjects and the presence of Candida albicans in their saliva. It was found that the subjects who showed signs and symptoms of Candida had more than 400 colony-forming units (CFU) of Candida in per ml of the saliva and represented chronic cases of Candidiasis while the rest of them who didn’t show any signs or symptoms of Candidiasis had less than 400 CFU/ml. So, the findings of this study give an insight as to the threshold of Candida (400 colony-forming units) in the saliva, where one can be normal and healthy or have a Candida infection. These findings can be more useful for a saliva lab test, but prove that the saliva can be an indication of Candida overgrowth or not.

Both the above studies show that Candidiasis can be easily detected through the saliva test and there are valid reasons to back this up. Firstly the presence of excess glucose in saliva which can result from diabetes mellitus or some other drug-therapy a person has undergoing, may give rise to Candida growth and secondly a saliva test can help with the diagnosis of Candidiasis easily and detect whether it is a chronic case or not.
