When To Get Tested? Sample Required? Test Preparation Needed? Looking for Test Results? Looking for Reference Ranges? What is being tested? How is the sample collected for testing? Is any test preparation needed to ensure the quality of the sample? No test preparation is needed. See More. See Less. Accordion Title. How is it used?
When is it requested? It is also repeated at regular intervals for many conditions, including: Monitoring treatment of anaemia , polycythaemia or dehydration. Monitoring the need for or effectiveness of blood transfusions, monitoring of ongoing bleeding to check its severity. What does the test result mean?
Is there anything else I should know? How do you treat anaemia? Can I measure my PCV at home? This test is performed by trained laboratory personnel.
Is anyone more at risk for abnormal PCV values? Good question! TP is a measurement of only the proteins in plasma, not looking at non-protein solids also present think triglycerides - then think about lipemic patients and what you get on the refractomoeter. TS is taking into account all of the solids in plasma.
Our refractometers are calibrated to read TP and automatically subtract about 2. Maybe I missed it, but I didn't see any values listed in the article. Thank you, Samantha Bliven.

Thank you Megan, that's very helpful. What is the difference between TS and TP? Thank you! So helpful, loved the little chart here at the end!!
Was looking for this info too. Start a Free Trial. All medical members can easily perform the test but interpreting them is the tricky part. The readings can provide a lot of information regarding the patient's status and also help plan the next treatment step.
A lower number of the PCV means that the RBC count loss is due to reasons such as blood loss, cell destruction and less bone marrow production.
By looking at the tube out of the centrifuge, you can get an idea of the WBC content as well. This buffy coat normally lies between the plasma and red cell layer. This shouldn't be counted as a part of the PCV test. There isn't any special preparation required for the PCV test. Also, any medications that you've been taking have to be relayed to the doctor. If there are any medical problems which are underlying too, you need to fast before taking a test. A low PCV implies that the patient has a low number of red blood cells and is suffering from anaemia.
The doctor may ask the patient to undergo further tests to determine the underlying causes of anaemia. Treatment will be given accordingly. The PCV test is calculated with the help of an automated analyser which means that it isn't directly measured.
By multiplying the red cell count with the mean cell volume, doctors get the final amount. PCV is slightly less accurate than the hematocrit as they include small amounts of the plasma from the blood that is generally trapped in between two red cells.
By tripling the haemoglobin concentration and dropping the units, an estimated hematocrit can be determined in percentage. The PCV can also be determined with the help of the of a capillary tube and the centrifuging heparinised blood in it at around RPM for roughly five minutes.
