The formula to calculate the Neutrophil-Lymphocyte Ratio (NLR) is:
\[ \text{NLR} = \frac{\text{N}}{\text{L}} \]
Where:
The neutrophil-lymphocyte ratio (NLR) is a measure derived from the counts of neutrophils and lymphocytes in the blood. It is calculated by dividing the number of neutrophils by the number of lymphocytes. This ratio is used as an indicator of the balance between the body’s immune response and inflammation. Elevated NLR values can indicate an increased inflammatory response, which may be associated with various medical conditions such as infections, cardiovascular diseases, and cancers. Conversely, lower NLR values may indicate a more balanced immune response. The NLR is a simple and cost-effective marker that can provide valuable insights into a patient’s health status.
Let's assume the following values:
Using the formula:
\[ \text{NLR} = \frac{5000}{1500} \approx 3.33 \]
The Neutrophil-Lymphocyte Ratio (NLR) is approximately 3.33.
