Description
Why It’s Done:
The PCV/HCT test is used to:
• Evaluate for anemia (low red blood cell levels).
• Detect polycythemia (high red blood cell levels).
• Assess hydration status, as dehydration may falsely elevate hematocrit levels.
• Monitor blood loss in conditions like internal bleeding or surgery.
• Track treatment response in conditions affecting red blood cell production, such as kidney disease, bone marrow disorders, or during chemotherapy.
• Help diagnose underlying nutritional deficiencies, chronic diseases, or other blood disorders.
Preparation:
• No special preparation is usually required.
• Fasting is not necessary, unless this test is part of a larger panel that requires it.
• Inform your doctor if you have had recent surgery, blood transfusion, or significant fluid loss (vomiting, diarrhea, or burns), as these may affect the results.
• A blood sample will be collected from a vein in your arm for testing.
