What is a hematocrit reader used for?
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.
What does hematocrit level tell you?
A hematocrit test measures how much of your blood is made up of red blood cells. Red blood cells contain a protein called hemoglobin that carries oxygen from your lungs to the rest of your body. Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions.
What does it mean if hematocrit is high?
If your hematocrit is high, it means that you have more red blood cells than is considered healthy. High hematocrit may be caused by [4:1]: Heart disease. Dehydration.
What are symptoms of low HCT?
When a person has low hematocrit levels they tend to present with the following symptoms:
- pale complexion.
- low energy.
- trouble breathing.
- irregular heartbeat.
- cold hands or feet.
What is hematocrit and why is it important?
A hematocrit is a simple blood test done to measure the red blood cells in a person’s blood. Red blood cells (erythrocytes) are important because they carry oxygen through your body. A low or high red blood cell count can indicate a medical condition or disease.
What is normal hematocrit?
Normal ranges vary substantially with race, age and sex. The definition of normal red-blood cell percentage also varies from one medical practice to another. Generally, a normal range is considered to be: For men, 38.3 to 48.6 percent. For women, 35.5 to 44.9 percent.
What diseases cause low hematocrit?
Low hematocrit results can indicate:
- Blood loss.
- Leukemia or other bone marrow problems.
- Iron and vitamin deficiency, including folate, vitamin B12, and vitamin B6.
- Too much water in the body.
- Kidney disease.
- Thyroid abnormality.
- Immune destruction of red blood cells.
How do you keep your hematocrit normal?
You can reduce your hematocrit through the following dietary modifications:
- Avoiding iron supplements 
- Eating more bran (it interferes with iron absorption) 
- Staying hydrated 
- Avoiding alcohol 
- Eating more grapefruit 
- Getting more antioxidants 
What are the symptoms of high hematocrit?
What does it mean if your hematocrit is high?
- Shortness of breath.
- Flushed skin.
- Joint pain.
How can I lower my hematocrit levels quickly?
How can I raise my hematocrit fast?
What can I do to increase my low hematocrit? Increasing the consumption of red meat (liver in particular), fish and shellfish (oysters, clams, shrimp, and scallops), dried fruit (apricots, prunes, and peaches), green leafy vegetables, beans, iron fortified breads and cereals, all rich in iron, may help.
How to read the hematocrit?
Using either a hematocrit reader or any ruled apparatus, measure the length of the column of the packed red cells and divide it by the length of the whole column of blood (cells and plasma), as in Figure 151.1. To obtain the hematocrit, multiply this number by 100%. Average all readings obtained from the different microhematocrit tubes.
What is the normal value of hematocrit?
Abbreviated HCT , hematocrit is a blood test that measures the percentage of red blood cells in the blood. Normal hematocrit levels in adult males can range from 42-54 percent. In adult women, normal hematocrit levels can range from 38-46 percent.
What is manual hematocrit?
The hematocrit can also be determined by a manual method using a centrifuge. When a tube of blood is centrifuged, the red cells will be packed into the bottom of the tube. The proportion of red cells to the total blood volume can then be visually measured.
What are the effects of elevated hematocrit levels?
Elevated levels of hemoglobin or hematocrit can cause you to feel faint, impair your vision, and leave you with other problems like an enlarged spleen. Knowing the causes can help you find the right treatment and fix the problem as soon as possible.
