High hematocrit (HCT) levels can be a symptom of various diseases and health conditions.
It is worth understanding what hematocrit is, when an HCT test should be performed, how to prepare for it and what the norms are for children, women and men. In addition, find out what are the causes and effects of elevated HCT and what the consequences of low HCT levels may be. This article will help you understand why it is important to monitor your hematocrit level and what steps to take if it deviates from the norm.
What is hematocrit?
Hematocrit is an indicator determining the percentage of red blood cells (erythrocytes) in the blood in relation to the total blood volume. This is an important parameter that helps assess the body’s ability to transport oxygen to tissues and organs. A high hematocrit level may indicate a health risk.
When should an HCT test be performed?
HCT testing may be recommended in a variety of situations. It is most often performed as part of routine blood tests, but may also be ordered by a doctor if specific health problems are suspected, such as anemia, dehydration, heart or kidney disease. It is also part of the standard blood test carried out during periodic examinations.
Hematocrit – course of the examination. how to prepare for blood collection?
The HCT test involves taking a blood sample, most often from an antecubital vein. It does not require any special preparation, but it is recommended to follow a few rules before doing it. For example, it is worth fasting, avoiding excessive physical exercise just before the test, and informing the doctor about any medications or supplements you are taking that may affect the results.
Hematocrit – norms for children, women and men
Hematocrit norms may vary depending on age and gender. For men, they usually range from 38% to 50%, for women, from 34% to 44%, and in children, these values may be even different, depending on age and body development.
High hematocrit – causes and effects of increased hct
High hematocrit levels can be caused by various factors, such as dehydration, smoking, chronic lung diseases, or increased production of red blood cells. This can lead to serious problems such as pulmonary embolism, stroke or thrombosis.
Low hematocrit – causes and effects of hct below normal
Low hematocrit levels may be a symptom of anemia, hemorrhages, chronic liver diseases or nutrient deficiencies. The effects of low HCT can be equally serious, including fatigue, headache, pale skin, and trouble concentrating.
Hematocrit – price/reimbursement and referral for testing
HCT testing is often reimbursed by the healthcare system, especially if it is ordered by a doctor for a specific health problem. However, the price of the test may vary depending on the medical facility. It is worth consulting a doctor to obtain a referral for the test.
Your suggestions
If you have concerns about your hematocrit level or have symptoms that may suggest problems with HCT, do not hesitate to consult your doctor. A professional assessment and appropriate testing can help diagnose and treat any medical conditions.
