Vaginal pH

The vaginal canal should reside at an acidic pH between 3.7- 4.5. This acidity is caused by lactobacillus bacteria, and to a lesser extent bifidobacterium, producing lactic acid through their metabolism of glycogen in the vaginal lining. An acidic environment helps protect against infections by inhibiting the growth of harmful bacteria and yeasts. The pH test was conducted at the same time as the vaginal swab, and was self-reported by the patient using our online form. Please bear in mind that this is a basic marker, and must be reviewed alongside other scores for completeness.

The following classifications have been provided and individual test results will be allocated one of the outcomes shown below.

4.0 and 4.4: WITHIN RANGE

If the pH falls within the purple area, either 4.0 or 4.4, this indicates significant presence of a lactic acid producing bacteria, which is positive. Please review all markers for completeness.

4.7 and 5.0: JUST OVER IDEAL RANGE

If the pH falls slightly out of range, either 4.7 or 5.0, this may indicate a slight shift away from a microbiome dominated by lactobacillus. Please review all markers for completeness.

5.3, 5.5, 5.8 and 7.0: OUT OF IDEAL RANGE

If the pH falls out of range, specifically higher than 5.3, this may indicate a lack of lactic acid producing bacteria. Please review all markers for completeness.
