Yes, that's correct. Diff-Quik stain stains red blood cells pink and white blood cells purple due to differences in the staining properties of these cells. This differential staining helps in distinguishing between the two types of blood cells under a microscope.

Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
Anemic hypoxia reflects poor oxygen delivery due to too few red blood cells (RBCs) or from RBCs that contain abnormal or too little hemoglobin. This leads to reduced oxygen-carrying capacity in the blood, resulting in inadequate oxygen reaching the body's tissues and cells.
The primary source of RBCs in the adult human being is the bone marrow in the shafts of the long bones?
That's correct. Red blood cells (RBCs) are primarily produced in the bone marrow of long bones like the femur and the humerus in adult human beings. The bone marrow contains stem cells that differentiate into specialized blood cells, including RBCs.
What is the compatibility testing for agglutination of donor RBCs by the recipeints' serum?
Compatibility testing involves mixing donor red blood cells (RBCs) with recipient serum to check for agglutination. If agglutination occurs, it indicates incompatibility between the donor RBCs and recipient serum, suggesting a mismatch that could lead to a transfusion reaction. Testing is crucial to ensure safe blood transfusions.
What is the significance of RBC enumeration?
RBC (red blood cell) enumeration is important for diagnosing conditions like anemia, polycythemia, or other blood disorders. It can also provide information about oxygen-carrying capacity and overall health status. Monitoring RBC levels helps in assessing response to treatments and identifying any potential health risks.
How do you compare RBC from WBC?
Red blood cells (RBCs) are responsible for oxygen transport, while white blood cells (WBCs) are part of the immune system and help fight infections. RBCs are biconcave and lack a nucleus, whereas WBCs are larger, have a nucleus, and can be classified into different types like lymphocytes and neutrophils. RBCs have a longer lifespan (about 120 days) compared to WBCs, which have a shorter lifespan and are constantly replenished by the bone marrow.
What tube color for RBC?
The tube color for testing red blood cells (RBCs) is typically purple, which corresponds to a tube containing the anticoagulant ethylenediaminetetraacetic acid (EDTA). This additive helps to prevent clotting and preserve the integrity of the RBCs for analysis.
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 significance of Enumerated?
low rbcs count shows anaemia high rbcs count show polycythemia vera. rbcs enumerations shows the bonemarrow how much active.
RBC is drawn in what color tube?
RBCs are typically drawn in a purple or lavender-top tube, which contains the anticoagulant EDTA. This type of tube is used for hematology studies and to prevent clotting of the blood sample.
What test is used to determine the volume of packed RBCs?
Hematocrit measures the volumeof packed RBCs as a percentage of blood volume.
How identify RBC?
Red blood cells (RBCs) are identified by their characteristic biconcave disc shape when viewed under a microscope. They lack a nucleus, have a diameter of around 6-8 micrometers, and appear red due to the presence of the protein hemoglobin. A simple blood smear stained with a dye such as Giemsa or Wright stain can be used to visualize and identify RBCs.
What happens if rbc's and saline solutions are mixed?
If red blood cells (RBCs) are mixed with a saline solution, the RBCs may undergo hemolysis, where they rupture and release their contents into the solution. This can lead to changes in the osmotic balance and potentially cause damage to the RBCs. It is important to handle RBCs carefully to prevent hemolysis and maintain their function.
What is the percentage RBCs in your body?
45%
What is known as the graveyard of RBCs?
Appendix
What is the condition of too few RBCs or of RBCs with hemoglobin deficiencies?
Anaemia, kidney dysfunction, bleeding-excessive, vitamine B12 deficiency
Why we can not extract DNA from RBCs?
Red blood cells do not have a nucleus or organelles, which are essential for DNA extraction. Without a nucleus, RBCs lack the DNA needed for extraction. White blood cells, on the other hand, do have a nucleus and contain DNA, making them suitable for DNA extraction.
