Abstract
Plasma Malondialdehyde (MDA) value was measured by simple fluorometric assay for lipoperoxide in blood plasma (Yagi's method).
The conclusion are as follows: Yagi's method is simple and suitable for clinical purposes. The measurement must be completed as quickly as possible, since prolonged measurement, using old specimens or employing needless manipulations thereby increasing the time span during measurement, gives falsely higher plasma MDA value.
Although the reason is obscure, the frequency of subjects having distinctly elevated plasma MDA value is significantly higher in the pregnant women than in identically aged unpregnant females.
For determination of normal MDA value in plasma, futher examination is necessary.
