HemDirect Hemoglobin Test

Intended Use

The SERATEC® HemDirect test serves the rapid identification of human blood for forensic purposes. The detection is based on the determination of human hemoglobin in the sample by a specific antigen/antibody reaction. The result is interpreted visually by the appearance of a red test result line in hemoglobin positive samples. The test is easy to perform (no training necessary) and can be used directly at the crime scene, if required.

Originally the SERATEC® HemDirect test was developed for the determination of occult blood in stool samples and was used for the early detection of colon cancer.

Specificity

The SERATEC® HemDirect Test shows no cross reactivity with bovine, dog, rabbit, cat, pig, wild boar, horse, chicken, sheep, mule, goat or red deer hemoglobin. Blood of primates and blood of ferret reacted positive in the test.

Sensitivity

Qualitative Analysis (without SeraQuant): cut-off at 40 ng/mL Hb.
Quantitative Analysis (SeraQuant): down to 10 ng/mL Hb.
