Plateletcrit (PCT)

Why test for Plateletcrit (PCT) at Symbion VIP Diagnostics Ahmedabad ?

PCT is the volume occupied by platelets in the blood as a percentage and calculated according to the formula PCT = platelet count × MPV / 10,000 (25-27). Under physiological conditions, the amount of platelets in the blood is maintained in an equilibrium state by regeneration and elimination. The normal range for PCT is 0.22–0.24%. In healthy subjects, platelet mass is closely regulated to keep it constant, while MPV is inversely related to platelet counts. Genetic and acquired factors, such as race, age, smoking status, alcohol consumption, and physical activity, modify blood platelet count and MPV.

A low platelet count is known as thrombocytopenia. Thrombocytopenia can occur as a result of a separate disorder, such as leukemia or an immune system problem. Or it can be a side effect of taking certain medications.

Symptoms

Thrombocytopenia may be mild and cause few signs or symptoms. In rare cases, the number of platelets may be so low that dangerous internal bleeding occurs. Treatment options are available.

Thrombocytopenia signs and symptoms may include:

Easy or excessive bruising (purpura):

Purpura, also called blood spots or skin hemorrhages, refers to purple-colored spots that are most recognizable on the skin. The spots may also appear on organs or mucous membranes, including the membranes on the inside of the mouth.

Petechiae:

Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs. Petechiae are tiny purple, red, or brown spots on the skin. They usually appear on your arms, legs, stomach, and buttocks. You might also find them inside your mouth or on your eyelids.

• Prolonged bleeding from cuts
• Bleeding from your gums or nose
• Blood in urine or stools
• Unusually heavy menstrual flows
• Fatigue
• Enlarged spleen

Jaundice:

In jaundice, the skin and whites of the eyes look yellow. Jaundice occurs when there is too much bilirubin (a yellow pigment) in the blood—a condition called hyperbilirubinemia.

The laboratory test results are NOT to be interpreted as results of a "stand-alone" test.
