Autoimmune Screen
ANA Test Interpreter
Enter your ANA titer and pattern with symptoms to understand which diseases your result suggests, what labs to order next, and whether it might be a false positive.
Titer-weighted disease probabilities (SLE, Sjogren's, SSc, MCTD, RA, myositis)
Pattern-specific interpretation (homogeneous, speckled, centromere, nucleolar, cytoplasmic, peripheral)
False positive probability with individual risk factor breakdown
Targeted next labs and referral guidance
▲
Muscle Enzymes
CK (Creatine Kinase) Interpreter
Enter your CK level and symptoms to determine whether the elevation suggests inflammatory myopathy, statin myopathy, rhabdomyolysis, hypothyroidism, cardiac injury, or exercise.
Severity classification with visual elevation scale
Differential probability across 8 causes
Rhabdomyolysis alert when values exceed 10,000 U/L
MSA panel guidance and statin management pathways
◇
RA Serology
RF + Anti-CCP Interpreter
Enter your rheumatoid factor and anti-CCP results with joint symptoms to understand the probability of RA versus false positive causes including hepatitis C, Sjogren's, and SLE.
Dual seropositivity logic (RF + anti-CCP vs single positive)
False positive breakdown by cause (HCV, age, sarcoidosis, infection)
Seronegative RA pathway and erosive disease guidance
Pre-DMARD baseline lab recommendations
△
Inflammation Markers
CRP + ESR Interpreter
Enter your CRP and ESR values with symptoms to understand what elevated inflammation markers mean - including the dissociation pattern specific to SLE and the markedly elevated ESR seen in GCA and PMR.
CRP vs ESR dissociation pattern interpretation (SLE, acute vs chronic)
Giant cell arteritis and PMR pattern detection
Malignancy B-symptom flagging with urgent guidance
Differential covering infection, autoimmune, IBD, malignancy
How the Interpreters Work
1
Enter Your Values
Type in the numbers exactly as they appear on your lab report. No unit conversion needed.
2
Add Your Symptoms
Select the symptoms and clinical context that apply. More detail produces a more precise interpretation.
3
Review Probabilities
See animated probability bars showing which conditions your result is most consistent with, and why.
4
Get Next Steps
Receive a prioritized list of follow-up labs, interpretation of false positive risk, and referral guidance.

Clinical use notice. These interpreters provide educational support based on published literature on test characteristics and disease associations. Probability estimates are qualitative approximations, not validated predictive models. They are intended to support clinical reasoning, not replace it.
