In lupus, the ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein) levels can vary depending on the activity and severity of the disease, as well as individual variations in response to the disease.
However, in general, a normal ESR for women under 50 is less than 20 mm/hr, and for men under 50, it is less than 15 mm/hr. For individuals over 50, normal ESR levels may be slightly higher.
CRP levels in healthy individuals are usually less than 10 mg/L, and levels above 10 mg/L indicate inflammation or infection. In lupus, CRP levels may be elevated during active disease flares.
It’s important to note that the ESR and CRP levels alone cannot be used to diagnose or monitor lupus activity. Other clinical and laboratory assessments are needed for proper diagnosis and management of the disease.
