How do you perform a Microhematocrit?
How do you perform a Microhematocrit?
For the microhematocrit method, after filling the blood in a capillary tube, the two ends of the tube (commonly 75 mm long, 1 mm diameter) are sealed with clay sealant or heat. Then, it is centrifuged at a rate of 11000 to 12000 rpm for 4 to 5 min.
What is a Microhematocrit centrifuge?
Microhematocrit centrifuges are used for determination of volume fractions of erythrocytes (red blood cells) in blood and for separation of micro volumes of blood and solutions. It provides hematocrit values (HCT) for testing in biochemistry, immunity, genetics, blood separation and for general clinical tests.
What precaution should be observed when performing a Microhematocrit?
What safety precautions should be observed when performing a microhematocrit? Observe Standard precautions; use plastic or Mylar-coated self-sealing tubes; close centrifuge lids securely; never open centrifuge until rotor has stopped; dispose of all sharps in appropriate containers.
What is the purpose of using a hematocrit centrifuge?
The haematocrit centrifuge is intended to provide laboratory tests for haematocrit values in the fields of biochemistry, microbic immunity genetics, and blood separation.
What is a microhematocrit tube used for?
Aside from the microhe- matocrit test, microhematocrit capillary tubes are used in various capacities such as filling a hemacytometer chamber in body fluid cell counts or making a blood smear. These capillary tubes can be nonheparinized (plain) or laced with heparin.
How does a microhematocrit centrifuge work?
Microhematocrit centrifuges are intended to aid in the diagnosis of blood disorders and diseases. By applying centrifugal force, it is possible to separate suspended particles in a fluid or to separate liquids that have different densities.
How does a Microhematocrit centrifuge work?
How do you use a Microhematocrit centrifuge?
Procedure
- Fill two capillary tubes approximately 2/3 to 3/4 full with the well-mixed blood sample.
- Seal the dry end of the capillary tube by placing it into the sealing clay at a 90o angle.
- Place the capillary tubes in the microhematocrit centrifuge with the sealed end toward the periphery.
- Centrifuge for five minutes.
How do you use a microhematocrit centrifuge?
What is the importance of centrifuging a microhematocrit tube?
When centrifuging a microhematocrit tube, it is important to: Plug one end of the tube with clay. What instrument would the technician use to measure both the urine specific gravity and the protein levels of blood?
What are the uses of centrifuge?
A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel.
What are the different Microhematocrit tube types?

How are microhematocrit centrifuges used in blood work?
Microhematocrit Centrifuges. By applying centrifugal force, it is possible to separate suspended particles in a fluid or to separate liquids that have different densities. In particular, microhematicrit centrifuges can be used to determine the ratio of the volume of red blood cells to the total volume of blood (hematocrit).
Which is hematocrit centrifuge does EKF Diagnostics use?
HemataStat II™ is a hematocrit centrifuge delivering quantitative readings for up to six blood samples from a single 60 second spin. EKF Diagnostics’ HemataStat II™ is a micro hematocrit centrifuge that provides a quantitative hematocrit reading for up to six blood samples from one 60 second spin.
What kind of glass is used in hematocrit centrifuge?
The HemataStat II™ Hematocrit Centrifuge combines easy maintenance with a high degree of user safety, for example, heparinized ClearCrit™ tubes are used to collect the blood sample and are available in plastic, glass or Mylar® coated glass, designed for maximum user safety.
Why do you need small sample of blood for microhematocrit?
Because microhematocrit centrifuges use microcapillary tubes to hold samples, very small samples of blood are required for testing.
