Abstract

A kit and method for collecting a saliva sample for subsequent biologic assay that avoids collection contact with the biohazardous saliva sample. The kit includes a container, a preservative solution that is retained in the container and a saliva collection device. A subsequent laboratory assay performed by conventional techniques specific to the biologic of interest provides results comparable to those obtained from blood or urine samples. The kit allows an employee to remain at his or her place of business and requires only a minor inconvenience during testing.

Claims

1. A kit for the collection and preservation of a saliva sample for subsequent assay of a biologic therein comprising:

a container;

a saliva collection device, said saliva collection device including a salivation catalyst; and

a preservative solution retained within said container.

2. The kit of claim 1, wherein the container comprises a resealable tube.

3. The kit of claim 2, wherein the resealable tube comprises a polyethylene transfer vial.

4. The kit of claim 1, wherein the saliva collection device comprises a transfer pipette having a compression end and an intake end.

5. The kit of claim 1, wherein the salivation catalyst comprises a food flavoring.

6. The kit of claim 5, wherein the food flavoring is selected from a group consisting of lemon, peppermint, spearmint and orange flavorings.

7. The kit of claim 1, wherein the preservative solution comprises:

sodium chloride, NaHPO₄ and NaH₂PO₄ in an aqueous concentration to provide a 50 mM phosphate solution; and

0.5-2.0 g sodium benzoate.

8. The kit of claim 7, wherein the preservative solution comprises a pH of 6.2.

9. The kit of claim 1, wherein the preservative solution comprises a fungicide.

10. The kit of claim 1, wherein the preservative solution comprises a bactericide.

11. A method of assaying for a biological comprising the steps of:

providing a container;

providing a preservative solution within the container;

providing a saliva collection device, the saliva collection device including a salivation catalyst;

collecting at a first location a saliva sample directly from a mouth of a user using the saliva collection device;

depositing the saliva collection device having the saliva sample into the container; and

sealing the container having the saliva collection device against spillage and tampering.

12. The method of claim 11, further comprising the step of shipping the container having the saliva collection device to a second location.

13. The method of claim 12, further comprising the step of assaying the saliva sample and preservative solution subsequently for a biologic at a second location.

14. The method of claim 11, further comprising the step of assaying the saliva sample and preservative solution subsequently for a biologic at a second location.

15. The kit of claim 11, wherein the container comprises a resealable tube.

16. The kit of claim 15, wherein the resealable tube comprises a polyethylene transfer vial.

17. The kit of claim 11, wherein the saliva collection device comprises a transfer pipette having a compression end and an intake end.

18. The kit of claim 11, wherein the salivation catalyst comprises a food flavoring.

19. The kit of claim 18, wherein the food flavoring is selected from a group consisting of lemon, peppermint, spearmint and orange flavorings.

20. The kit of claim 11, wherein the preservative solution comprises:

sodium chloride, NaHPO₄ and NaH₂PO₄ in an aqueous concentration to provide a 50 mM phosphate solution; and

0.5-2.0 g sodium benzoate.

21. The kit of claim 11, wherein the preservative solution comprises a fungicide.

22. The kit of claim 11, wherein the preservative solution comprises a bactericide.
