[LAL test used for detection of undesirable biologically active substances in biopreparations].
Detection of bacterial endotoxin was performed in four groups of biopreparations: IVIG, virus and bacterial vaccines and antibiotics. The 44 samples of biopreparations were tested by the qualitative LAL-test (gel-clot) and some of them (22 samples) by the quantitative, LAL-test (chromogenic end-point). The concentration of endotoxin in 10 samples of IVIG was in the range from 0.457 EU/ml to 19.46 EU/ml. Only 4 of them did not exceed the limit recommended by FDA for human globulins (5 EU/ml). In the 9 samples out of 10 samples of virus vaccines the presence of endotoxin was in the range from 0.06 to 0.15 EU/ml. The concentration of endotoxin in 10 samples of bacterial vaccines determined by gel- clot method was below sensitivity of test (2 EU/ml). In antibiotics we did not find the presence of endotoxin in the range recommended by Ph. Eur. 1995 limits (0.1-0.2 EU/ml). The presented data show the necessity for requirements elaboration for each type of biopreparations.
