Vaginal indicator to detect biomarkers of good health
View Patent ↗A diagnostic kit for biomarkers of beneficial vaginal health is described. The kit includes a first detection zone within which a D-lactic acid detection signal is capable of being generated, wherein the presence or quantity of D-lactic acid, is determinable from the D-lactic acid detection signal. The kit further includes a second detection zone within which a hydrogen peroxide detection signal is capable of being generated, wherein the presence or quantity of hydrogen peroxide, is determinable from the hydrogen peroxide detection signal.
1. A diagnostic kit for biomarkers of beneficial vaginal health comprising:
a sample pad;
a lateral chromatographic medium, the lateral chromatographic medium defining a first detection zone within which a D-lactic acid detection signal is capable of being generated, the D-lactic acid detection signal comprising a color change generated from a non-diffusively immobilized chromogen that is contained within the first detection zone, the D-lactic acid detection signal being generated in response to an enzyme-catalyzed reaction of D-lactic acid present in a sample, wherein the quantity of D-lactic acid present in the sample is determinable from the D-lactic acid detection signal, the chromatographic medium further defining a second detection zone within which a hydrogen peroxide detection signal is capable of being generated, the hydrogen peroxide detection signal comprising a color change generated from a non-diffusively immoblized chromogen that is contained within the second detection zone, wherein the presence or quantity of vaginal hydrogen peroxide present in a sample is determinable from the hydrogen peroxide detection signal, the lateral chromatographic medium providing for lateral flow from the sample pad through the first detection zone and through the second detection zone; and
an absorbent material downstream of the lateral chromatograhic medium.
2. A diagnostic test kit as defined in claim 1 , wherein the first detection zone comprises D-lactate dehydrogenase.
3. A diagnostic test kit as defined in claim 2 , wherein the first detection zone further comprises diaphorase.
4. A diagnostic test kit as defined in claim 1 , wherein the first detection zone comprises D-lactate oxidase.
5. A diagnostic test kit as defined in claim 1 , wherein the first detection zone comprises a redox dye.
6. A diagnostic test kit as defined in claim 1 , wherein the second detection zone comprises peroxidase.
7. A diagnostic test kit as defined in claim 1 , wherein the second detection zone comprises redox dye.
8. A diagnostic test kit as defined in claim 1 , wherein the diagnostic test kit is positioned in an absorbent article.
9. A method for detecting biomarkers of beneficial vaginal health comprising:
i) contacting a test sample with the diagnostic kit of claim 1 ;
ii) determining the presence or quantity of D-lactic acid from the D-lactic acid detection signal; and
iii) determining the presence or quantity of vaginal hydrogen peroxide from the hydrogen peroxide detection signal.
10. A method as defined in claim 9 , wherein the first detection zone comprises D-lactate dehydrogenase.
11. A method as defined in claim 10 , wherein the first detection zone further comprises diaphorase.
12. A method as defined in claim 9 , wherein the first detection zone comprises D-lactate oxidase.
