A healthy result should fall into the range 0 - 1.3 mmol/mol creatinine.

The presence of organic compounds such as p-Hydroxybenzoate in the urine may point towards significant dysbiosis (=impaired microbiota). p-Hydroxybenzoat may reflect intestsinal overgrowth, usually accomanied by microbal hyperpermeability.

insert the value from you 4-Hydroxybenzoic test result.

What does it mean if your 4-Hydroxybenzoic result is too high?

4-Hydroxybenzoic Acid is a marker for intestinal dysbiosis. Results may also show elevated values as a result of ingestion of foods such as jams and pie fillings containing paraben preservatives. The use of probiotics and the exclusion of paraben-containing foods is the first treatment consideration.
