Tissue specimen bottle with color indicator in lid verifying and confirming presence of human tissue or blood contained in specimen bottle
View Patent ↗A method and apparatus for visually confirming and verifying the presence of human tissue or blood in a tissue specimen collection bottle and includes a test pad that inserts into the undersurface of a lid of a specimen bottle which undergoes a chromogenic reaction confirming the presence of human tissue or blood in said specimen bottle.
1. A verification method for confirming the presence of tissue in a tissue specimen bottle comprising:
a. providing a specimen bottle with a lid that has a chromogenic test pad in a bottom portion of the lid which can contact contents of the specimen bottle, wherein the test pad changes color in the presence of tissue,
b. contacting the contents of the specimen bottle with the bottom portion of the lid,
c. determining if a color change has occurred in the test pad,
d. correlating a color change in the test pad with the presence of tissue in the specimen bottle and no color change with the absence of tissue in the specimen bottle.
2. The method of claim 1 wherein said test pad comprises a sheet of absorbent paper.
3. The method of claim 1 wherein the specimen bottle comprises a clear specimen bottle.
4. The method of claim 1 wherein further the test pad changes color in the presence of blood.
5. The method of claim 4 , wherein the test pad comprises a guaiac compound and a peroxygen compound.
6. The method of claim 5 wherein the guaiac compound comprises guaiacolsulfonate.
7. The method of claim 5 wherein the guaiac compound comprises guaiacolsulfonate and the peroxygen compound comprises potassium monopersulfate.
8. The method of claim 5 wherein the peroxygen compound comprises a solid peroxygen compound.
9. The method of claim 8 wherein the peroxygen compound comprises potassium monopersulfate.
