Test Kit Update
New, smaller kits – with BioHealth’s still exceptional stability
As a result of BioHealth’s continued commitment to quality, we’re pleased to announce the development of smaller, more convenient kits for tests consisting solely of the following markers (see the list of tests in the table below).
- Cortisol (Saliva)
- DHEA-S (Saliva)
- Secretory IgA (Saliva)
- Small Intestinal Bacterial Overgrowth (SIBO – Breath)
- Bile Acids, Indican, Lipid Peroxides (Urine)
Tests and Panels Now Available in Smaller Kits
- Adrenal Stress Profile (#201)
- Adrenal Stress Profile with Insomnia Sample (#201C)
- Adrenal Stress Profile with SIgA (#201-S)
- Cortisol (#251)
- Cortisol Diurnal Rhythm (#204A)
- HPA Stress Profile (#201A)
- HPA Stress Profile with Insomnia Sample (#201A-C)
- HPA Stress Profile with SIgA (#201A-S)
- HPA Stress Profile with CAR (#201-CAR)
- HPA Stress Profile with CAR & SIgA (#201-S-CAR)
- Metabolic Assessment Tests (#101, #107, #108, #109)
- Secretory IgA (#310)
- SIBO Breath Test (#900)
Stability of Saliva for Cortisol, DHEA-S, and Secretory IgA
In-house studies and published literature demonstrate that the analytes cortisol, DHEA-S, and secretory IgA are stable at ambient temperatures. In the past, we used a single thermal kit design which protects even the most sensitive analytes (melatonin and progesterone, for example). However, the variation in stability between ambient and cold transport methods – for cortisol, DHEA-S, and secretory IgA – is clinically insignificant, and requests from clients for a smaller kit warranted this change.
Sensitive Analytes Need Thermal Protection
Many of the analytes BioHealth tests on saliva necessitate cold storage during transport to the lab. Two of these, testosterone (relatively stable) and progesterone (known to be unstable), were evaluated in a study in which we compared the shipping temperatures and thermal protection (or lack thereof) of 5 other labs to BioHealth. What we found was a definitive difference in the accuracy of test results when shipped by a thermally controlled method.
