Platelet concentration and platelet volume distribution in healthy cats.

摘要: An electronic particle counter and size analysis system were used to determine platelet count, mean volume (MPV), heterogeneity (SD of volumes), mass values in feline platelet-rich plasma (PRP) prepared by brief centrifugation blood. Electronic counts correlated well with manual done phase microscopy over a count range 5,000/microliters 840,000/microliters (r = 0.93). Variability was not significantly different. However, due differential stratification concentration PRP, on aspirated, mixed PRP less variable (P than 0.01). Reference values, determined blood from 25 healthy adult cats, count: 296,000 850,000/microliters; MPV: 11.0 18.1 fl; heterogeneity: 5.8 10.6 fl, mass: 4.0 11.4 microliters/ml There direct relationship between MPV an inverse count. Platelet constant different layers. Aliquots near the top had lower 0.001) did aliquots bottom layer. During 4 hours after sample collection, there progressive decrease increase MPV, but changes significant. When platelets incubated counting fluid, slight 1.5 hours. By 2.5 hours, significant 0.05).
