At-Home Blood Pregnancy Test Kit

Abstract

Disclosed is an at-home blood pregnancy test kit that can identify the presence of hCG in a blood sample to detect pregnancy in female mammals. The present kit includes a housing having a sample strip that is in fluid communication with a sample pad for holding a blood sample, a test pad, and a conjugate pad. The housing further includes a test window and a push button for releasing a reagent that can react with hCG. The reagent and the test pad include antibodies that can bind with hCG antigens to detect presence of the same. The test window is adapted to display a symbol that indicates a negative pregnancy test result in the absence of hCG, or display a symbol that indicates a positive pregnancy test result in the presence of hCG.

I claim: 
     
         1 . An at-home blood pregnancy test kit, comprising:
 a housing having an upper end with an opening and an interior volume having a sample pad, a conjugate pad, and a test pad therebetween;   a sample strip extending outward from said opening;   said sample strip adapted to collect a blood sample and deliver it to said sample pad;   a push button adapted to release a reagent at said conjugate pad;   wherein said reagent comprises a first antibody that binds with hCG antigens to detect presence of hCG in said blood sample;   said reagent combining with said blood sample to create a blood-reagent mixture at said test pad;   wherein said test pad comprises a second antibody that binds with hCG antigens;   wherein said test pad is adapted to indicate presence of hCG in said blood sample, whereby presence of hCG in said blood sample above a predetermined threshold provides a positive pregnancy test result and presence of hCG in said blood sample below said predetermined threshold or absence of hCG in said blood sample provides a negative pregnancy test result.   
     
     
         2 . The at-home blood pregnancy test kit of  claim 1 , wherein said opening is centrally located on said upper end of said housing. 
     
     
         3 . The at-home blood pregnancy test kit of  claim 1 , wherein said sample pad, said conjugate pad, and said test pad are in fluid communication. 
     
     
         4 . The at-home blood pregnancy test kit of  claim 1 , wherein said conjugate pad is directly subjacent to said push button. 
     
     
         5 . The at-home blood pregnancy test kit of  claim 1 , wherein said test pad comprises a test portion and a control portion;
 said control portion adapted to display a marking when in direct contact with said blood-reagent mixture;   said test portion adapted to display a plus sign when presence of said hCG in said blood sample exceeds said predetermined threshold;   said test portion adapted to display a minus sign when presence of said hCG in said blood sample is absent or below said predetermined threshold.   
     
     
         6 . The at-home blood pregnancy test kit of  claim 5 , wherein said test portion and said control portion are visible through a test window on said housing. 
     
     
         7 . The at-home blood pregnancy test kit of  claim 1 , wherein said predetermined threshold is 5 mlU/ml.
