[Comparison of the streptozyme test with titration of antistreptolysin, antistreptokinase and antistreptohyaluronidase].
Streptozyme is a new serologic assay which is able to evidentiate 5 antistreptococcal antibodies at the same time (TAS, ASHA, ASK, DNase, NADase). This test has been carried out on 355 samples together with TAS, ASK and ASHA methods in order to value this method comparatively. The results showed that Streptozyme is a poorly reliable technique, looking at the false-positive or negative results obtained, but principally looking at the phenomena of no good reproducibility. We feel that at present it cannot be used in substitution of the classic serologic methods.
