P-LCR Blood Test

P-LCR Blood Test

P-LCR Blood Test, P-LCR typically stands for platelets Large Cell Ratio. It is a parameter of large platelets in the bloodstream. Large platelets are sometimes called Young platelets and their presence can indicate various underlying conditions or disorders.

The Platelets Cell Ratio (P-LCR) is calculated as follows:

P-LCR=(Number of Large platelets/Total platelets count)x 100

Normal Range of P-LCR

  • The normal range for P-LCR may vary between laboratories, but generally, it is considered to be between 9% and 17%.
  • However, reference ranges can differ based on the specific laboratory’s equipment and methods.

High P-LCR(Thrombocytopenia with Increased Large Platelets):


1. Immune Thrombocytopenia Purpose (ITP):

  • An autoimmune disorder that leads to a decreased platelet count and an increase in large platelets.

2. Viral Infection:

3. Myeloproliferative Disorders:

  • Conditions like essential thrombocythemia or chronic myeloid leukemia can lead to a higher P-LCR.

Causes of Low P-LCR( Normal Decrease Platelets Size):

1. Bone Marrow Disorders:

  • The condition that affects platelet production or maturation in bone marrow can lead to a lower P-LCR.

2. Megaloblastic Anemia:

  • A type of anemia characterized by enlarged red blood cells can sometimes affect platelet size and result in a lower P-LCR.

3. Certain Medications:

  • Some medications, such as chemotherapeutic drugs, can affect platelet size and lower the P-LCR.


  • It is important to remember that the interpretation of P-LCR values should always be done in conjunction with other clinical information, and any concerns or questions about your blood test results should be discussed with a healthcare provider.
  • They can provide a more accurate assessment of your specific situation and recommend any necessary follow-up or treatment.

  1. […] MPV (Mean Platelet Volume), The mean platelet volume (MVP) is the average size of your Platelet. When the MPV value is high in blood and platelet count is low, it means that the bone marrow is producing platelets quickly due to increased destruction of platelets. Low MPV means your platelets are similar in size, which means older platelets are in circulation, which means your bone marrow is not producing enough new platelets. […]
