Quick answer
The Packed Cell Volume (PCV) Test costs ₹180 at Live Line Health Care. Shows what percentage of your blood is made up of red cells, which helps doctors assess anaemia. No fasting is needed. It uses a blood sample and the report is usually ready the same day. Book home sample collection or visit any of our 45 centres.
Also known as: Packed Cell Volume, Packed Cell Value, PCV Count, Haematocrit, Hematocrit, HCT
What is the PCV Test?
The Packed Cell Volume (PCV) test shows how much of your blood, by volume, is made up of red blood cells. It is also called the haematocrit, or HCT on many reports, and the result is a percentage. A PCV of 42% means that red cells fill 42% of the sample and the rest is mostly plasma, the liquid part of blood. Modern analysers work this out from the size and number of red cells, while the traditional method spins blood in a fine tube and measures the packed layer.
Because PCV depends on both red cells and plasma, it moves for two different reasons. It falls when red cells are lost, as in anaemia, and it rises when the body loses fluid, as in dehydration. That second use makes it important in dengue: a rising PCV can be an early sign that plasma is leaking out of blood vessels, often just as the fever seems to be settling. Doctors therefore often request PCV with the platelet count during a fever. In most people PCV is roughly three times the haemoglobin value. A CBC already includes this reading, so this test suits repeat follow-up.
What it measures: The percentage of your blood volume occupied by red blood cells.
Parameters included (1)
- Packed Cell Volume (%)
Why is this test done?
- Tracking concentration of the blood in dengue, along with the platelet count
- Assessing dehydration from vomiting, diarrhoea or heat exposure
- Detecting and following anaemia
- Following polycythaemia or a persistently high haemoglobin
- Checking the response after major bleeding or a blood transfusion
When should you get tested?
- Dengue or suspected dengue, especially as the fever begins to settle
- Dry mouth, passing little urine or dizziness on standing
- Tiredness, pale skin or breathlessness on effort
- Headaches or blurred vision with a known high red cell count
- Heavy periods or recent blood loss
How to prepare for the PCV Test
- 1There is no need to fast. Keep taking fluids as your doctor advised, since PCV reflects your hydration.
- 2If you are being followed for dengue, carry your earlier PCV values, as doctors read the change from your own baseline.
- 3Tell staff about any intravenous fluids or blood transfusion in the last day or two, since they change the reading.
PCV Test normal range
| Parameter | Typical reference range |
|---|---|
| Men | 40–50% |
| Women | 36–46% |
| Pregnant women | 33% or abovethe normal rise in plasma lowers PCV in pregnancy |
Newborns and infants have very different values. Some reports write PCV as a decimal, so 0.42 means 42%. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A low PCV usually goes with low haemoglobin and suggests anaemia. Extra fluid in the circulation, as in pregnancy or after intravenous fluids, can also dilute it.
- A high PCV commonly reflects dehydration and falls when fluids are replaced. If it stays high, doctors consider smoking, long-standing lung disease or polycythaemia.
- In dengue, a rise of 20% or more from your usual level is treated as a sign of plasma leakage, especially if platelets are also falling. This needs urgent medical review.
- A sudden fall in PCV in someone who remains unwell with dengue can mean internal bleeding and needs hospital care.
PCV Test – FAQs
What is the price of the PCV Test?
The Packed Cell Volume (PCV) Test costs ₹180 at Live Line Health Care, at all 45 centres and for home sample collection.
Are PCV and haematocrit the same test?
Yes. PCV (packed cell volume) and haematocrit measure the same thing, and reports often shorten it to HCT. Some prescriptions say PCV count or packed cell value, which are other names for the same test. You do not need to book them separately.
Why is PCV checked in dengue?
Severe dengue can make fluid leak from blood vessels, so the blood becomes more concentrated and the PCV rises. A rising PCV with falling platelets warns doctors that shock could develop. This is why it is often repeated during the critical days when the fever is coming down. Follow your doctor's schedule.
What does high PCV mean?
It usually means your blood is more concentrated than normal, most often due to dehydration. Smoking, high altitude, long-standing lung disease and polycythaemia can also raise it. Your doctor will look at your haemoglobin and fluid status. A high PCV along with dengue needs urgent medical review.
What does low PCV mean?
A low PCV generally means fewer red cells than expected, as happens in anaemia from iron deficiency, blood loss, or low vitamin B12 or folate. It can also be diluted by pregnancy or extra fluid. A CBC and iron tests can help your doctor find the cause.
Is PCV the same as haemoglobin?
No, but they are linked. Haemoglobin measures the oxygen-carrying protein, while PCV measures the space taken up by red cells. In most people PCV is about three times the haemoglobin, so an Hb of 14 g/dL suggests a PCV near 42%. A wide gap may need a closer look.
Do I need this test if I already have a CBC report?
Usually not on the same day, because a CBC already includes PCV along with other values. This test is for repeat readings when your doctor wants only the PCV, for example during dengue follow-up. Check your CBC report first to avoid testing twice.
Where can I get the PCV Test done?
At any of our 45 Live Line Health Care centres in 40 cities across Andhra Pradesh and Telangana, including Hyderabad, Visakhapatnam, Warangal, Kakinada and Nellore, or book home sample collection.
