Introduction:
The P LCR Blood Test (Platelet-Larger Cell Ratio) is an important diagnostic tool that provides valuable insights into the size distribution of platelets in the bloodstream. Platelets play a crucial role in blood clotting and wound healing, and abnormalities in their size and quantity can indicate several health issues, ranging from inflammatory diseases to blood disorders.
This blog aims to explain the purpose of the P-LCR Blood Test, how to interpret the results and its significance in diagnosing various medical conditions.
What Is the P-LCR Blood Test?
The Platelet-Larger Cell Ratio (P-LCR) test measures the proportion of larger platelets in the blood compared to the total number of platelets. Platelets, also known as thrombocytes, are vital for stopping bleeding and facilitating clotting. The P-LCR test focuses explicitly on the giant, often younger platelets, which can provide deeper insights into the body’s platelet production and functionality.
The P-LCR test is usually conducted as part of a Complete Blood Count (CBC) with a differential. It helps assess platelet function and can be used to monitor several health conditions, including inflammatory diseases, heart problems, and hematologic disorders.
Average Range for the P-LCR Blood Test
The normal range for the P-LCR test typically falls between 13% and 35%, although this can vary slightly depending on the laboratory and the equipment used. A result within this range generally indicates that the platelet size distribution is normal and that there is no significant issue with platelet production or destruction.

However, it’s essential to consult with your healthcare provider to interpret the result in conjunction with other test results and your overall clinical condition.
What Does a High P-LCR Blood Test Mean?
A high P-LCR value means there is a higher proportion of larger platelets than usual. This can indicate several potential health conditions:
- Inflammatory Diseases: Conditions like rheumatoid arthritis or lupus can lead to increased platelet production, including larger platelets.
- Recovery from Thrombocytopenia: After a period of low platelet count, the body may produce larger platelets in an attempt to replenish its platelet supply.
- Cardiovascular Diseases: Larger platelets are often associated with increased clotting activity, potentially elevating the risk of heart attack or stroke.
- Myeloproliferative Disorders: These disorders cause abnormal growth of blood cells, including an increase in platelet size and number.
If your test results show a high P-LCR blood test, further investigations may be required to identify the underlying cause.
What Causes Low P-LCR?
A low P-LCR value suggests that there is a reduced percentage of large platelets in the bloodstream. This can occur due to several factors:
- Bone Marrow Disorders: Conditions like aplastic anaemia or certain forms of leukaemia can cause the bone marrow to produce fewer large platelets.
- Viral Infections: Certain viral infections may affect the bone marrow’s ability to produce platelets, leading to a lower percentage of large platelets.
- Increased Platelet Destruction: Disorders like immune thrombocytopenic purpura (ITP) cause the body to destroy platelets faster than they are produced, leading to a reduction in large platelets.
A low P-LCR result may indicate that the body is struggling with platelet production or that platelets are being destroyed more quickly than usual.
How Is the P-LCR Blood Test Performed?
The P-LCR Blood Test is a simple blood test that typically involves drawing blood from a vein in your arm. The sample is then analyzed in a laboratory to determine the platelet count and the size distribution of the platelets. The test is often part of a routine Complete Blood Count (CBC).

Cost of the P-LCR Blood Test
The cost of the P LCR Blood Test varies depending on several factors, including geographic location, the healthcare provider, and whether the test is part of a larger panel (such as a CBC). On average, the cost can range from INR 200 to INR 1500, depending on the testing facility.
Conclusion:
The P LCR Blood Test offers valuable insights into platelet health, helping to diagnose a range of conditions that affect blood clotting and platelet production. Whether the result is high or low, understanding the significance of the P-LCR can help healthcare providers identify underlying health issues and make informed treatment decisions.
If you’re experiencing symptoms related to blood clotting or have been diagnosed with any condition that affects platelets, the P LCR test is an essential part of your diagnostic journey. Always consult with your doctor to interpret the results and get a comprehensive understanding of your health status.
