The detection of fetal hemoglobin in bloodstains by means of thin-layer immunoassay.

A method for the detection of fetal hemoglobin in bloodstains by means of thin-layer immunoassay is described. The equivalent of 0.01 microL of blood containing 0.18 to 0.24 microgram of fetal hemoglobin may be detected by this method. Studies with stains up to two years old and blind studies have shown these methods to be sufficiently sensitive and specific to be of value in forensic serology.
