Influence of coagulation parameters on bleeding rates
Platelet count Quick test PTT
Reference range ≥ 70,000/μl ≥ 70 % < 50 s
Findings in relation to biopsy 42.5% (n = 948) 43.4% (n = 968) 34.8% (n = 775)
Biopsy in patients not meeting full coagulation criteria 1.2% (n = 11) 5.1% (n = 49) 1.4% (n = 11)
Most significant deviation from reference range 32,000/μl 45% 66 s
OR [95%-CI] 1.000 [0.997-1.004] 0.970 [0.0943-0.999] 1.078 [1.014-1.146]
