What is PCV in blood report?
A hematocrit (he-MAT-uh-krit) test measures the proportion of red blood cells in your blood. Red blood cells carry oxygen throughout your body. Having too few or too many red blood cells can be a sign of certain diseases. The hematocrit test, also known as a packed-cell volume (PCV) test, is a simple blood test.
What is normal PCV count?
Published data from Europe and North America indicate that for non-iron-deficient adult Caucasian males, the normal mean packed cell volume (PCV) is 0.46 and the 2.5-97.5 percentile interval is 04.0-0.53. Corresponding values for adult Caucasian females are: mean PCV 0.42; 2.5-97.5 percentile interval 0.36-0.48.
Why PCV count is low?
uses of packed cell volume test A low PCV implies that the patient has a low number of red blood cells and is suffering from anaemia. The doctor may ask the patient to undergo further tests to determine the underlying causes of anaemia. Treatment will be given accordingly.
In which condition PCV is high?
In polycythemia vera (PCV), the body makes too many red blood cells, leading to a thickening of the blood. It can be associated with an elevated platelet count and an enlarged spleen. This slow-developing disease is linked to a mutation in the gene JAK2, which regulates the production of blood cells.
What causes high PCV?
The most common cause of increased PCV is dehydration, and with adequate fluid intake, the PCV returns to normal. However, it may reflect a condition called polycythaemia where there are too many red cells.
Is 33% PCV normal?
A normal range of PCV generally depends on the person taking the test. In females, the normal range is 35.5 to 44.9%. In males, 38.3% to 48.6% is the normal PCV range. For pregnant females, the normal PCV is 33-38%.
What are the symptoms of high PCV?
Weakness or fatigue. Skin symptoms such as itching after a shower or bath, burning, or a red face. Heavy sweating, especially during sleep. Blurred or double vision and blind spots.
Is PCV 39 normal?
The proportion of the total volume of whole blood that red blood cells occupy (commonly called the packed cell volume or haematocrit) is normally in the range 39%– 51% for males and 36%–48% for females ( Fairbanks and Tefferi 2000 , 2001).
