SIRI reflects the balance between pro-inflammatory cells (neutrophils, monocytes) and lymphocytes. Elevated SIRI is associated with poor outcomes in cancer, cardiovascular disease, and critical illness. It's particularly useful for predicting survival and treatment response.

The Systemic Inflammation Response Index (SIRI) combines neutrophil, monocyte, and lymphocyte counts to assess systemic inflammation and immune function.
High Systemic Inflammation Response Index (SIRI) levels above the standard range may indicate an underlying health condition that warrants further evaluation.
Low Systemic Inflammation Response Index (SIRI) levels below the standard range may indicate an underlying health condition that warrants further evaluation.

Normal and optimal Systemic Inflammation Response Index (SIRI) ranges can vary by sex, age, and lab methodology. Review your result with a qualified clinician for personalized interpretation.

High SIRI: Usually asymptomatic but indicates heightened inflammatory state. May be associated with underlying disease symptoms.
High SIRI: Active cancer, severe infections, chronic inflammatory diseases, critical illness. Low SIRI: Healthy immune balance, good prognosis.
Systemic Inflammation Response Index (SIRI) can be ordered through Vitals Vault without a doctor referral, then completed at CLIA-certified Quest Diagnostics locations nationwide. After checkout, you receive clear draw instructions, digital requisition details, and a structured report that explains whether your result is in standard range, optimal range, or needs follow-up review.
Start by identifying the root cause, then use targeted nutrition, training, sleep, stress, and follow-up retesting to verify improvement. Systemic Inflammation Response Index (SIRI) should be optimized with a personalized plan, not guesswork.
You should speak with a clinician if Systemic Inflammation Response Index (SIRI) is significantly outside the reference range, trending in the wrong direction across repeat tests, or accompanied by symptoms like fatigue, chest discomfort, dizziness, weight change, or persistent inflammation signs. Immediate medical care is important for severe symptoms, not just abnormal numbers in isolation.
A practical retesting cadence for Systemic Inflammation Response Index (SIRI) is every 8 to 12 weeks after major lifestyle, nutrition, or medication changes, and every 3 to 6 months for stable long-term tracking. Faster cadence is useful when values are clearly abnormal, while maintenance cadence helps confirm durability once results stabilize.
You can compare Essential ($99), Advanced ($199), and Max ($399) plans during checkout to confirm Systemic Inflammation Response Index (SIRI) inclusion before purchasing. If Systemic Inflammation Response Index (SIRI) is not in your selected tier, you can upgrade plans or add targeted testing so your panel matches your goals, symptoms, and retesting strategy.
Systemic Inflammation Response Index (SIRI) is included in our comprehensive biomarker panels, processed at CLIA-certified Quest Diagnostics locations nationwide.
