Lab Tests for Lupus Monitoring
Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect virtually any organ system, including your joints, skin, kidneys, and blood. Ongoing lab monitoring is critical for tracking disease activity, catching flares early, and preventing organ damage — especially kidney involvement. Key tests include ANA for diagnosis, inflammatory markers for activity, and renal function panels for kidney monitoring. JustLabs lets you order lupus monitoring labs online at transparent prices between rheumatology appointments, no doctor visit required.
Recommended Tests
Understanding Your Results
| Test | Normal Range | Low Means | High Means |
|---|---|---|---|
| ANA | Negative (<1:40) | SLE less likely (but not ruled out) | Positive in 95%+ of lupus patients |
| hs-CRP | <1.0 mg/L | Low systemic inflammation | Active inflammation — possible flare |
| Sed Rate (ESR) | M: 0–22; F: 0–29 mm/hr | Minimal inflammation | Elevated inflammation — track with CRP |
| Creatinine (Renal) | 0.6–1.2 mg/dL | Normal kidney function | Possible kidney involvement (lupus nephritis) |
