The final interpretation

☀ If both the Immune Colloidal Method and Chemical Method show positive, the final result is positive which indicates bleeding in specimen.

☀ If the Immune Colloidal Method shows positive while Chemical Method shows negative, this indicates occult bleeding. The concentration of hemoglobin in the sample is much lower. The final result is also positive.

☀ If the Immune Colloidal Method shows negative while Chemical Method shows positive, this probably because the high concentration of hemoglobin causing antigen excess, and have hook effect. It is suggested that dilute the sample 100 times and retest, if Immune Colloidal Method shows positive, this indicates the enteron begin to bleed profusely; if Immune Colloidal Method still shows negative, this indicates some substances interfered, the result should be negative.

☀ If both the Immune Colloidal Method and Chemical Method show negative ,the final result is nagative.

☀ If any one of Immune Colloidal Method and Chemical Method shows invalid, the test result is invalid, please retest with a new one.
