[Measurement of electric impedance as a screening method for diagnosing haemorrhagic diatheses (author's transl)].
Changes in electrical impedance during blood clotting have been previously described. Personal measurements on blood of 18 healthy donors and 29 patients with various disorders of clotting gave reproducible results with this method. There was a marked difference between normal subjects and those with bleeding diatheses regardless of type. There was good correlation between impedance changes and the thrombelastogram, the former being more sensitive in diagnosing haemorrhagic disorders. Further studies are required to evaluate its place as a screening method in these conditions.
