[Determination and interpretation of carboxyhemoglobin in traces of biological material]

The author investigated the possibility of assessment of the carboxy haemoglobin level in blood stains and particles of tissues which contain at least minimal amounts of blood pigment. For the examination methods were modified which are used for similar estimations in blood. In the blood stains the decline of carboxy-haemoglobin was investigated in relation to some external influences. The author investigated also the ability of haemoglobin to react with carbon monoxide at different periods after the development of blood stains.
