Table 5.

Positive predictive values (PPVs—probability that the patient has the condition when restricted to those patients who tested positive) in the deceased, ICU and hospital ward groups and negative predictive values (NPVs—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 range values (out of range for PPV; in range for NPV) creatinine, azotemia, RBC (men and women), Hb (men and women), Hct, MCV, MCH, MCHC, RDW, monocytes, eosinophils, basophils, WBC, neutrophils, lymphocytes, PLT and PCT. Significant scores are shown in bold.
