The Claim
The Berkeley saliva test strip shows a stronger correlation with lab-measured salivary nitrite (r = 0.76) than the Neogenesis strip (r = 0.59) in overweight, non-smoking adults aged 40–65.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In overweight, non-smoking adults aged 40–65, the Berkeley saliva test strip measures salivary nitrite levels more closely to laboratory results than the Neogenesis strip.
See the scientific wording
The Berkeley saliva test strip demonstrates a stronger correlation with lab-measured salivary nitrite (r = 0.76) than the Neogenesis strip (r = 0.59) in overweight, non-smoking adults aged 40–65, suggesting it may be a more reliable semi-quantitative tool for research or personal monitoring of oral nitrite.
Dietary nitrate enters the bloodstream, gets pulled into saliva by glands in the mouth, and is turned into nitrite by bacteria on the tongue. This nitrite in saliva can be measured to estimate how much nitrate the body is processing, and the accuracy of this measurement depends on how well the test strip detects the nitrite produced by these bacteria.
What the research says
1 studyStudy: Validation of two Point-of-care Tests against Standard Lab Measures of NO in Saliva and in Serum
The study found that the Berkeley saliva strip matches lab results better than the Neogenesis strip, so it’s a more accurate tool for checking nitrite levels in saliva. This means it’s slightly better for people who want to track their oral health at home.
