MLR is elevated in various inflammatory and malignant conditions. Higher MLR values are associated with worse outcomes in cancer, cardiovascular disease, and infections. It's useful for prognosis assessment and monitoring disease activity.

The Monocyte-to-Lymphocyte Ratio (MLR) is an inflammatory marker that reflects the balance between innate (monocyte) and adaptive (lymphocyte) immune responses.
Reference ranges may vary slightly between laboratories. The values below represent commonly accepted clinical ranges.
Ranges shown are general guidelines. Consult your provider for personalized interpretation.
| Biomarker | Reference range | Interpretation |
|---|---|---|
Monocyte-to-Lymphocyte Ratio (MLR) (Male — Standard) | 5–8 [pH] | Standard lab reference range |
Monocyte-to-Lymphocyte Ratio (MLR) (Female — Standard) | 5–8 [pH] | Standard lab reference range |
High Monocyte-to-Lymphocyte Ratio (MLR) levels above the standard range may indicate an underlying health condition that warrants further evaluation.
Low Monocyte-to-Lymphocyte Ratio (MLR) levels below the standard range may indicate an underlying health condition that warrants further evaluation.
The Monocyte-to-Lymphocyte Ratio (MLR) is an inflammatory marker that reflects the balance between innate (monocyte) and adaptive (lymphocyte) immune responses.
Standard range men: 5–8 [pH]; women: 5–8 [pH]. Always interpret ranges in clinical context, not as a stand-alone diagnosis.

High MLR: Generally asymptomatic but indicates underlying inflammatory or disease processes. May be associated with fatigue, unexplained weight loss, or symptoms of the primary condition.
High MLR: Cancer, coronary artery disease, tuberculosis, severe infections, autoimmune disorders. Low MLR: Generally favorable, indicating balanced immune function.
Monocyte-to-Lymphocyte Ratio (MLR) 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. Monocyte-to-Lymphocyte Ratio (MLR) should be optimized with a personalized plan, not guesswork.
You should speak with a clinician if Monocyte-to-Lymphocyte Ratio (MLR) 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 Monocyte-to-Lymphocyte Ratio (MLR) 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 Monocyte-to-Lymphocyte Ratio (MLR) inclusion before purchasing. If Monocyte-to-Lymphocyte Ratio (MLR) is not in your selected tier, you can upgrade plans or add targeted testing so your panel matches your goals, symptoms, and retesting strategy.
