Which lens is used for RBC count?
Which lens is used for RBC count?
COUNTING THE RED BLOOD CELLS UNDER MICROSCOPE square as described above, using the 40x Objective lens.
How is erythrocyte count calculated?
Calculation
- Area of each of the five squares in which cells are counted.
- Therefore, total area counted.
- Depth of chamber = 1/10 mm.
- Therefore, the volume in which cells are counted.
- Now, in 1/50 cu mm of diluted blood, the number of erythrocyte counted = E.
- Number of erythrocyte in one cu mm in diluted blood = E x 50.
What is WBC?
White blood cells are part of the body’s immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

Background: Human blood appears to be a red liquid to the naked eye, but under a microscope we can see that it contains four distinct elements: white blood cells. and platelets.
How powerful can a microscope see blood cells?
At 400x magnification you will be able to see bacteria, blood cells and protozoans swimming around. At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up.
How can you tell the difference between a WBC and a microscope?
When viewed under the microscope, the smear will show different types of leukocytes as well as red cells. Students will be able to differentiate white blood cells based on their shape and nucleus. * Neutrophils are often first responders during infection. Death of many neutrophils form pus.
What causes high erythrocytes?
Some of the common conditions that can result in elevated erythropoietin due to chronic hypoxia or poor oxygen supply include: chronic obstructive pulmonary disease (COPD, emphysema, chronic bronchitis), pulmonary hypertension, hypoventilation syndrome, congestive heart failure, obstructive sleep apnea,
What causes elevated erythrocytes?
Moderately elevated ESR occurs with inflammation but also with anemia, infection, pregnancy, and with aging. A very high ESR usually has an obvious cause, such as a severe infection, marked by an increase in globulins, polymyalgia rheumatica or temporal arteritis.
What is normal erythrocytes?
In humans the normal mature erythrocyte is a biconcave disk without a nucleus, about 7.7 micrometers in diameter, consisting mainly of hemoglobin and a supporting framework called the stroma. Erythrocyte formation ( erythropoiesis) takes place in the red bone marrow in the adult, and in the liver, spleen, and bone marrow of the fetus.
What causes erythrocytes in urine?
Other reasons: There can be some other causes of erythrocytes in urine like; intense-frequent sexual activity, menstruation, prostate enlargement, injuries, viral infections.
