Lymphocyte-to-Monocyte Ratio (LMR)
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how Lymphocyte-to-Monocyte Ratio (LMR) changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Lymphocyte-to-Monocyte Ratio (LMR)?
A calculated ratio comparing two white-blood-cell types - lymphocytes and monocytes - as a general marker of immune balance.
This is a calculated value from a routine complete blood count (CBC): it divides your lymphocyte count by your monocyte count. A lower LMR can be associated with more systemic inflammation and, in research, less favorable outcomes, a higher LMR can be associated with a more balanced immune state. It is a general, non-specific signal rather than a diagnosis.
What to know about Lymphocyte-to-Monocyte Ratio (LMR)
Understanding Lymphocyte-to-Monocyte Ratio (LMR) means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
