LMR Formula:
| From: | To: |
The Lymphocyte To Monocyte Ratio (LMR) is a hematological parameter calculated by dividing the absolute lymphocyte count by the absolute monocyte count. It serves as a marker of systemic inflammation and has been studied as a prognostic indicator in various diseases.
The calculator uses the LMR formula:
Where:
Explanation: The ratio provides insight into the balance between these two important immune cell populations, which can reflect the body's inflammatory state.
Details: LMR has been associated with prognosis in various conditions including cancers, cardiovascular diseases, and inflammatory disorders. A lower LMR typically indicates a higher inflammatory state and has been correlated with poorer outcomes in many clinical studies.
Tips: Enter absolute lymphocyte and monocyte counts in cells/µL. Both values must be greater than zero for accurate calculation.
Q1: What is a normal LMR range?
A: Normal LMR values typically range between 2.0 and 6.0, though this can vary based on laboratory standards and population characteristics.
Q2: Why is LMR clinically significant?
A: LMR serves as an indicator of systemic inflammation and immune status, with prognostic value in various malignancies, cardiovascular diseases, and inflammatory conditions.
Q3: How should blood samples be collected for LMR calculation?
A: Standard complete blood count (CBC) with differential is sufficient. No special preparation is typically required.
Q4: Can LMR be used alone for diagnosis?
A: No, LMR should be interpreted in conjunction with other clinical findings, laboratory results, and patient history as it is a non-specific marker.
Q5: Does LMR change with age?
A: Some variations in lymphocyte and monocyte counts occur with age, but the clinical significance of age-related LMR changes requires further research.
