The packed cell volume (PCV) test is a common blood test used to measure the volume of red blood cells (RBCs) in a sample of blood. It is also known as the hematocrit test. The test is typically performed as part of a routine blood work panel or to diagnose and monitor conditions that affect the production or destruction of RBCs, such as anemia or dehydration.

To perform the PCV test, a healthcare provider or laboratory technician will draw a small sample of blood from a vein in the arm using a needle and a vacuum-sealed tube. The tube will contain an anticoagulant, such as heparin or EDTA, to prevent the blood from clotting. The sample will then be taken to a laboratory and centrifuged to separate the RBCs from other components of the blood, such as plasma and white blood cells.

After the blood has been centrifuged, the volume of the RBCs can be measured and expressed as a percentage of the total volume of the sample. This percentage is known as the packed cell volume. Normal values for the PCV range from about 37% to 55% in men and from about 37% to 47% in women, although values may vary slightly depending on the laboratory and the specific testing method used.

The results of the PCV test can help diagnose and monitor conditions that affect the production or destruction of RBCs, such as anemia, dehydration, or blood loss. Anemia is a condition in which the body does not have enough RBCs or the RBCs do not function properly. Dehydration occurs when the body does not have enough fluid, which can lead to a decrease in RBC volume. Blood loss can also result in a decrease in RBC volume.

In addition to the PCV test, other tests may also be performed to evaluate the function of RBCs and diagnose conditions that affect the production or destruction of RBCs. These tests may include a complete blood count (CBC), which measures the number and types of RBCs, white blood cells, and platelets in the blood, and a blood smear, which is a microscope examination of a thin layer of blood smeared on a microscope slide.

In conclusion, the packed cell volume test is a common blood test used to measure the volume of red blood cells in a sample of blood. It is typically performed as part of a routine blood work panel or to diagnose and monitor conditions that affect the production or destruction of RBCs. The results of the PCV test can help diagnose and monitor conditions such as anemia, dehydration, or blood loss, and may be used in conjunction with other tests to evaluate the function of RBCs.

PCV Test Normal Range: Result, Preparation and Procedure

A packed cell volume test is a blood test that measures the number of red blood cells, or RBCs, in your blood. For example, a test result may simply say 45 rather than 45%. It is an umbrella term that describes a group of lung diseases that make breathing difficult. It is generally done along with a full blood count test that is conducted to estimate the need for any blood transfusions and monitor the response to the blood transfusion treatment. Red blood cells carry oxygen throughout your body. A low proportion of red blood cells depletes this capacity.

The average lifespan of the RBCs in circulation is about 120 days. The only requirement is that your test should be done at a lab that follows proper safety measures. This is the reason why the value of PCV is lower in females. RBCs are produced in the erythropoietic cells of the bone marrow in response to the hormone erythropoietin that is secreted by the kidneys when the oxygen saturation of the blood is detected to be low hypoxia. Results Results from your hematocrit test are reported as the percentage of your blood volume that's composed of red blood cells. The packed cell volume PCV test is used to assess the proportion of blood made up of red blood cells that is available to help with the provision of oxygen throughout the body.

In some cases, the PCV value of 30% mild anemia is also observed. When the reports are ready, your healthcare provider will share the results with you. If bacteria are present in the sample, they will cause an increase in pressure inside it that will increase volume or decrease if they are removed.

In some cases, a high or low PCV value could be normal. Measuring the proportion of red blood cells in your blood can help your doctor make a diagnosis or monitor your response to a treatment. This contains a protein called haemoglobin that binds to oxygen for transport. Interpreting test results Although a hematocrit level is measured as a percentage, lab reports may or may not include a percentage symbol. Hence, the bone marrow continuously manufactures RBCs to maintain a steady concentration in the blood.

Accessed on 05 April 2018. Accessed March 24, 2016. What does a Packed Cell Volume Hematocrit test measure? High PCVs are common in people with chronic liver disease due to cirrhosis; however, some other causes are more serious, including leukemia, sickle cell disease, and thalassemia. An increased PCV generally means that the person is dehydrated, and there is a higher number of RBC production. What is the type of sample required? Your test will show a high PCV value if your red blood cell volume exceeds this quantity, while a low PCV value means that your red blood cells fall below the normal range.

With the unique combination of state-of-the-art technology, intuitive care, and clinical excellence, we are the healthcare destination for thousands of international patients in India. Micro method is preferred as it is rapid, convenient and requires less amount of blood. Cells settle down towards the bottom because of their greater density leaving the clear plasma on upper side.

It is done regularly as part of a checkup or to monitor your health if you are being treated for cancer or have an ongoing health condition. This is also called as hematocrit and expressed in percentage of original volume of blood or as decimal fraction. However, you may visit "Cookie Settings" to provide a controlled consent.

A normal range of PCV generally depends on the person taking the test. The red blood cells need to be at the right level for them to meet the oxygen demand of your body since they transport oxygen from your lungs to other areas of your body.
