Abstract

This disclosed method improves the accuracy of testing blood for the levels of contaminants, such as lead, cadmium and mercury, in individuals. The method comprises cleaning the area where the skin will be penetrated to obtain the blood sample to remove the contaminant to be measured in the blood. The cleansing is accomplished with a cleanser formulated to remove the contaminant to be measured in the blood from the surface of the skin, the pores, sweat ducts, hair follicles and sebaceous gland ducts. The method reduces contamination of the blood sample by contaminants on, and/or in the portion of the skin through which the blood sample is drawn. A premoistened wipe can also be used that mobilizes heavy metals from the skin surface, the skin pores, sweat ducts, hair follicles and sebaceous gland ducts, and is formed with a wipe substrate material selected for its affinity to bind the toxic materials.

Claims

1. A method for cleaning a blood sampling site on an individual prior to collection of a blood sample, the method comprising the steps of:

a) applying a contaminant-removing cleanser to the site to remove the contaminant to be measured in the blood from the surface of the skin, the pores, sweat ducts, hair follicles and sebaceous glands at the site, the cleanser comprising at least one surfactant and at least one contaminant-removing agent present in an amount of between 0.1% w/w to about 25% w/w of the cleanser; and

b) removing the skin cleanser from the site.

2. The method of claim 1 wherein the at least one contaminant-removing agent is a chelating agent.

3. The method of claim 1 wherein the at least one contaminant-removing agent is a phosphonate.

4. The method of claim 1 wherein the at least one contaminant-removing agent is a combination of a chelating agent and a phosphonate.

5. The method of claim 1 wherein the cleanser comprises:

a) a cationic surfactant;

b) an anionic surfactant

c) a phosphonate; and

d) an amine oxide.

6. The method of claim 1 wherein the at least one contaminant-removing agent is a terpene.

7. The method of claim 1 wherein the at least one contaminant-removing agent is a combination of a terpene and a phosphonate.

8. The method of claim 1 wherein the cleanser comprises two or more of:

a) a terpene;

b) a surfactant;

c) an alkanolamine;

d) an amine oxide; and

e) a phosphonate.

9. The method of claim 1 further comprising the step of scrubbing the site with a contaminant-removing substrate moistened with a contaminant-removing solution after removing the cleanser.

10. The method of claim 9 wherein the step of scrubbing the site with the substrate comprises simultaneously exfoliating dead cells on the site.

11. The method of claim 1 wherein the cleanser further comprises an abrasive and further comprising the step of exfoliating dead cells from the site simultaneously with applying the cleanser to the site.

12. The method of claim 1 wherein the step of applying the skin cleanser comprises:

a) applying water to the site; and

b) applying the skin cleanser to the site.

13. The method of claim 12 further comprising the steps of:

a) rinsing the site with water after applying the cleanser to the site; and

b) scrubbing the site with a contaminant-removing substrate moistened with a contaminant-removing solution after rinsing the site.

14. The method of claim 13 further comprising the steps of:

a) reapplying the cleanser to the site after rinsing the site and before scrubbing the site; and

b) re-rinsing the site with water prior to scrubbing the site.

15. The method of claim 1 wherein the step of removing the cleanser from the site comprises wiping the cleanser from the site.

16. The method of claim 15 further comprising the step of scrubbing the site with a contaminant-removing substrate moistened with a contaminant-removing solution after wiping the cleanser from the site.

17. The method of claim 16 further comprising the steps of:

a) reapplying the cleanser to the site after wiping the cleanser from the site and prior to scrubbing the site; and

b) re-wiping the cleanser from the site prior to scubbing the site.

18. The method of claim 15 further comprising the step of washing the site prior to wiping the cleanser from the site.

19. The method of claim 1 further comprising the step of disinfecting the site after removing the cleanser from the site.

20. The method of claim 18 wherein the step of disinfecting the site is performed simultaneously with scrubbing the site with a contaminant-removing substrate moistened with a contaminant-removing solution.

21. The method of claim 1 further comprising the step of disinfecting the site simultaneously with applying the cleanser to the site.

22. The method of claim 1 wherein the contaminant to be removed is selected from the group consisting of:

calcium, magnesium, lead, mercury, cadmium, manganese, strontium, barium, iron, cobalt, nickel, copper, zinc, thorium, radium and uranium.

23. A method for cleaning a blood sampling site on an individual prior to collection of a blood sample to remove a contaminant to be measured in the blood from the surface of the skin, the pores, sweat ducts, hair follicles and sebaceous glands at the site, the method comprising the steps of:

a) washing the site; and

b) scrubbing the site with a contaminant-removing substrate moistened with a contaminant-removing solution after washing the site.

24. A method for improving the blood flow at a blood sampling site, the method comprising the steps of:

a) applying a contaminant-removing cleanser to the site to remove the contaminant to be measured in the blood from the surface of the skin, the pores, sweat ducts, hair follicles and sebaceous glands at the site, the cleanser comprising at least one surfactant and at least one calcium-removing agent present in an amount of between 0.1% w/w to about 25% w/w of the cleanser; and

b) removing the skin cleanser from the site.
