Table 6.

Positive predictive values (PPV—probability that the patient has the condition when restricted to those patients who test positive) in the deceased, ICU and hospital ward groups and negative predictive values (NPV—probability that a patient who has a negative test result indeed does not have the condition) in the emergency group are based on the reference values (out of range for PPV; in range for NPV) for P/F ratio, CK, CK-MB, TNT, FBG, GGT, glycemia, CRP, INR, aPTT, LDH, albumin, D-dimer, MGB, AST, ALT, and ferritin (men and women—see Section 2). Significant scores are shown in bold.
