The WBC count was 10.6 × 103 cells/μL,
and the automated differential cell count showed 69% polymorphonuclear
leukocytes, 24% lymphocytes, 5% monocytes, and 1% eosinophils. The
hemoglobin level was 12.7 g/dL, and the hematocrit was 38.7%. The
chemistry panel was normal, except for mild increase in creatinine to
1.5 mg/dL and alkaline phosphatase of 189 U/L (normal, 30 to 140 U/L).
She had an albumin of 3.7 g/dL (normal, 3.3 to 4.7 g/dL), and a total
protein of 5.5 g/dL (normal, 5.8 to 7.7 g/dL). Urine analysis was
negative for hematuria and proteinuria. Antinuclear antibody,
cytoplasmic and perinuclear antineutrophilic cytoplasmic antibodies (by
enzyme immunoassay and fluorescence tests), rheumatoid factor, and
fungal serologies (for aspergillosis, histoplasmosis, and
coccidioidomycosis) were not detectable.
