Haematocrit, also known as packed cell volume (PCV), is the measurement of the proportion of blood that is made up of cells. It is usually presented as a percentage or fraction of cells in the blood. For example, a haematocrit or PCV of 50% means there are 50 millilitres of cells per 100 millilitres of blood.
Haematocrit is usually tested as part of a full blood count and can be used for a variety of reasons.
Why take a Haematocrit blood test?
A haematocrit blood test can help to identify a variety of illnesses and conditions. It can be used to monitor treatment for anaemia or dehydration.
A normal haematocrit for men is between 40 and 54% while for women it is between 36 and 48%. The test is based upon plasma volume and so, dehydration can affect the overall result. Many anaemias can be diagnosed with a haematocrit and haemoglobin reading.
