Answer

If the CRP is 3 mg/dL or higher and/or the ESR is 40 mm/hr or more, the next step is to obtain supplemental laboratory studies. Abnormal limits include the following:

  • Albumin 3 g/dL or less

  • Anemia for age

  • Elevated ALT level

  • Platelets >450,000 (after 7 days of fever)

  • WBC count 15,000/mm3 or greater

  • Urine WBC 10/hpf or greater
