title: [Demonstration of hemoglobin using the porphyrin test (author's transl)].
abstract: The demonstration of hemoglobin after its transformation into Porphyrin is specific and extremely sensitive. It is possible to detect amounts as small as a microgram. The use of sulphuric acid as a reagent is superior to the hydrochloricthioglycol acid method. After obtaining a speciman from a blood stain (usually through soaking) it is recommended that it be concentrated by allowing the speciman once again to dry out. Prejudicial effects due to the extreme sensitivity of this test are therefore avoided.
