Table 2. Laboratory Values for Patients With and Without Severe Disease.
| Laboratory studies (normal values) | Peak values, mean (range) | P value | |
|---|---|---|---|
| Nonsevere (n = 41) | Severe (n = 9) | ||
| C-reactive protein (≤10 mg/dL) | 4.45 (0.027-25.7) | 18.825 (12.69-25.78) | <.001 |
| Procalcitonin (≤0.08 ng/mL) | 0.74 (0.04-7.44) | 5.3 (0.13-29.89) | .03 |
| Ferritin (≤150 ng/mL) | NAa | 432.55 (178-1374) | NA |
| Interleukin 6 (≤5 pg/mL) | 139.52 (11.2-315.0) | ||
| D-dimer (≤0.5 μg/mL) | 4.87 (0.95-18.775) | ||
| Partial thromboplastin time (23.9-34.7 s) | 47.77 (32.4-108.5) | ||
| Prothrombin time (11.9-14.4 s) | 17.32 (13.7-20.7) | ||
Abbreviation: NA, not applicable.
SI conversion factors: To convert C-reactive protein to mg/L, multiply by 10; D-dimer to nmol/L, multiply by 5.476; ferritin to μg/L, multiply by 1.
a
Ferritin, interleukin 6, D-dimer, partial thromboplastin time, and prothrombin time values were not consistently obtained in patients with nonsevere disease.
