When counting RBCs and WBCs do you use a concentrated blood sample and a hemocytometer?
No, you will dilute the blood before putting it into the counting chamber (hemocytometer). RBC counts will typically be diluted with normal or isotonic saline, or a similar fluid. WBC counts will be diluted with a substance that will cause the lysis of non-nucleated RBCs (aka mature RBCs). The diluent used is usually 20% acetic acid, 1% HCl acid, Turk's acid (acetic acid and a stain), or 1% ammonium oxalate.

What is the function of hemocytometer in cell count?
A hemocytometer is a device with a small, precise grid for which the area and depth are known. It is used to count cells, though was originally used for counting blood cells. By counting the number of cells in a given sample space, a generalization can be made about the population, or entire sample.

What is RBC pipette?
An RBC pipette is a specialized glass tube used in hematology to measure the number of red blood cells in a blood sample. It is designed to hold a specific volume of blood for accurate cell counting and is typically used in conjunction with a hemocytometer or automated cell counter.
What is hemocytometer?
Hemocytometer-- An instrument used to count platelets or other blood cells.
What is hemacytometer counting?
uses a phase contrast microscope to view blood on a hemacytometer slide. A sample of the diluted blood mixture is placed in a hemacytometer, which is an instrument with a grid etched into its surface to guide the counting.
What is a blood sample?
A blood sample is a sample given for medical purposes as a blood test.
How do you distinguish an adult blood sample from a newborn infant sample?
Cord blood is a sample of blood taken from a newborn baby's umbilical cord
Hayems solution is used for determining what?
Hayem's solution is used for determining the total red blood cell count and the hemoglobin concentration in a given sample of blood. It is frequently used in hematology to assess various blood disorders and diseases.
When was Blood Sample created?
Blood Sample was created on 2005-09-21.
What is hemacytometer?
A hemocytometer (or hemacytometer) is a tool used to count cells (red blood cells, sperm, yeast...) under the microscope. It gives the number of cells per volume of fluid.
Why dilute the blood when doing red blood cell count?
Diluting the blood before a red blood cell count helps ensure accurate results by providing a standardized sample volume for counting. This allows for a more precise calculation of the number of red blood cells present per unit volume of blood. Dilution also helps prevent clumping of cells, which can interfere with accurate counting.
Can you tell a blood type by a urine sample?
No, you cannot determine a person's blood type from a urine sample. Blood type is determined by antigens on the surface of red blood cells, which are not present in urine. To determine blood type, a blood sample is needed for testing.
