Preliminary reference intervals and the impact of citrate storage time for thrombelastography in cats including delta and the velocity curve

Table 1 Results of the traditional coagulation profile obtained from 21 cats

Variable	TT (sec)	PT (sec)	aPTT (sec)	Fibrinogen (g/l)	D-dimers (μg/ml)
Mean	15.37	10.8	11.92	1.46	0.18
Median	15.4	10.8	12	1.48	0.2
Range	14–16.9	10.1–12.8	10.8–13	1.04–1.7	0.09–0.26
SD	0.82	0.56	0.74	0.17	0.05
RI (laboratory-internal^a)	13.4–19.1	9.9–12.2	10.8–14.0	0.6–2.2	0.0–0.3

Abbreviations: SD standard deviation, RI reference interval, TT thrombin time, PT prothrombin time, aPTT activated partial thromboplastin time, sec seconds
^aFor interpretation of the values, laboratory-internal reference intervals (RIs) established from 40 clinically healthy domestic shorthair cats using a robust method of untransformed data are additionally listed
