Twenty eight clinical chemical blood parameters were studied with respect to intra-individual variations. Both short term variations, within one day and during one week, and long term variations, during a six months period, were investigated in groups of 62, 16 and 274 individuals. Moreover, critical differences were calculated from the total variations,(More)
The intra-individual variations of 9 coagulation parameters were studied during short-term (within-one-day) and long-term (six months) periods. Two groups of healthy individuals (viz. 60 and 274 persons) were involved. Moreover, critical differences have been calculated from the total variations, comprising both biological and analytical variations. The(More)
Diamine oxidase in vaginal effluent is used as a parameter for ascertaining the state of fetal membranes. A new method using tritiated putrescine as a substrate is described for the determination of diamine oxidase in amniotic fluid and vaginal effluents. A number of tests are used for the diagnosis of premature rupture of fetal membranes. The described(More)
We determined serum ferritin, C-reactive protein (CRP), fibrinogen, and the erythrocyte sedimentation rate (ESR) in 73 patients with anemia of chronic disease. Nomograms of CRP, ESR, or fibrinogen vs ferritin concentrations were constructed and used to estimate the iron store in bone marrow. Iron stores estimated from the nomograms were compared with the(More)
The complete blood cell count and the differential leukocyte count have been studied for their variations within-one-day and during one week (short-term variations) and during a period of six months (long-term variations) with an automatic haematology analyser (H-6000, Technicon), in which some new parameters (large unstained cells, high peroxidase cells,(More)
A multicentre study for the detection of congenital hypothyroidism by enzyme-immunoassay of thyrotropin in filter paper blood spots is described. The method is accurate, with good precision and adequate sensitivity. No interference due to common blood constituents has been observed. Moreover, the TSH determination can easily be performed by photometric(More)
A rapid method for the estimation of sodium-(o-[(2,6-dichlorophenyl)-amino]-phenyl)-acetate (diclofenac-Na, Voltaren) used in the treatment of rheumatic diseases, in human blood plasma is described. The substance is extracted from acidified plasma with dichloromethane and acetylated after evaporation of the organic solvent, whereupon quantitation is(More)
