ASK® PREGNANCT ASSAY COMBO TEST-SERUM/URINE

PURPOSE 

     The ASK PREGNANCY ASSAY is, a colloidal gold antibody complex based chromatographic immunoassay, used for the qualitative determination of human chorionic gonadotropin (HCG) in serum or urine. This test is for professional use in obtaining a visual qualitative result for the early detection of pregnancy.

PRINCIPLE

The ASK PREGNANCY ASSAY COMBO TEST employs a combination of monoclonal and ployclonal antibodies to selectively identify HCG in the samples with a high degree of sensitivity. In less than 5 minutes, elevated levels of HCG equal to or greater 25 mIU/mL can be detected. At the level of claimed sensitivity, the ASK PREGNANCY ASSAY COMBO TEST shows no cross reactivity interference from the structurally related glycoprotein hormones hFSH, hLH and hTSH at high physiological levels.
    The principle of ASK PREGNANCY ASSAY COMBO TEST is as follows:
                                Diffuse through the 
(a)     Urine/Serum ------------------------------- > + anti-HCG
          absorbent reaction pack
 
    antibody-dye conjugate == > HCG Ag-Ab complex  
         (red color)
 
                                      Migrates via capillary action
(b)     HCG Ag-Ab complex ------------------------------------ >
                                    along the membrane
   
    + anti-HCG antibody === >
 
1.        A red line in the testing reaction zone (T): HCG25 mIU/mL.
2.        No line in the testing reaction zone (T): absence of HCG.
3.        A red line in the control reaction zone (C): the  reagent and reaction pack is functioning correctly.
4.        No red line in the control reaction zone (C): the reagent and reaction pack is functioning invalidly.
