Sharose PP Some strains produce fibrinolysin, dis-solve the clot after 4 hours of incubation at 35°C, and may appear to be negative if allowed to incubate longer than 4 hours. Because citrate-utilizing organisms may yield false-positive results, plasma containing ethylenediamine-tetraacetic acid (EDTA) rather than citrate should be used.
