Platelet-to-Lymphocyte Ratio
PLT / LYM
Description
"Platelet-to-Lymphocyte Ratio" test analyzes your platelet and lymphocyte levels to assess inflammation and immune system activity. It’s often used in evaluating cancer progression, cardiovascular risk, or autoimmune disease severity. A high ratio may signal active inflammation or stress, while a low ratio might reflect immune suppression. Doctors use this test to help interpret prognosis and refine care strategies. Tracking PLR levels over time helps monitor treatment response and guide long-term inflammation and immune system support.

Test Group Description
Basic Inflammation Group: This set of tests helps evaluate the body's inflammatory response, providing valuable information for diagnosing and managing inflammatory conditions. Blood Count Supplementary Group: This group includes additional tests beyond the standard complete blood count, offering supplementary information to further characterize blood composition and provide comprehensive insights into hematologic health. Complete Inflammation Group: Extensive tests offer a comprehensive assessment of inflammatory markers, yielding detailed insights into inflammation levels and related health conditions. Hematology Group: Tests within this group focus on evaluating various aspects of blood health and function. These assessments provide insights into red blood cells, white blood cells, platelets, and other components of the blood.

Key Reasons For Testing
Inflammatory Marker: Reflects the balance between platelet activation and lymphocyte-mediated immune response.
Prognostic Indicator: Predicts outcomes in cancer, cardiovascular disorders, and infections.
Risk Stratification: Identifies high-risk patients in sepsis, cancer, and severe diseases.
Response to Therapy: Tracks treatment efficacy, with trends indicating disease control or progression.
Prognostic Value in Critical Illness: Assesses outcomes like ICU admission and mortality in critically ill patients.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
