Plasma endotoxin level of healthy donors.
The plasma level of endotoxin was determined in 116 healthy blood donors. After a routine physical and laboratory investigations the endotoxin level was determined with Limulus amebocyte lysate assay (LAL-test) by the chromogenic kinetic method of Bio-Whittaker Co. (USA). Its sensitivity was 0.005-50 EU/ml. The plasma level of endotoxin in most of the healthy donors was less than 1 EU/ml (in the range of 0.01-1.0 EU/ml), but always measurable. The average +/- S.D. was 0.128 +/- 0.215 EU/ml. Because of the high standard deviation and high range of values, the data were distributed into two groups with the means of 0.05 +/- 0.022 EU/ml and 0.294 +/- 0.186 EU/ml. The difference between the groups was significant (p < 0.001). In conclusion, endotoxin can be measured in plasma of healthy individuals.
