Blood test
In an average blood test, 3 to 10 ml (1 to 3 teaspoons) of blood is collected from the body with a needle. This amount is not much, but doctors can learn a lot from this little blood. In a complete blood count (CBC), red blood cells, white blood cells and molecules are measured. It helps to assess a person's overall health and can identify various health problems, such as anemia and leukemia or bone marrow cancer. Your doctor may also order a blood test to diagnose viruses, hormones and other substances. In this report, 9 issues that were caught in the blood test were discussed.

| 9 things that are known in blood test |
Ability to conceive: A blood test can tell if a woman can conceive, said Dr. Nanjiato-Ghobashi. "A woman's blood test can tell the age of her egg cells, based on which the chances of getting pregnant can be estimated," she added.
Biological age: Your date of birth speaks to your chronological age or chronological age, some hereditary and lifestyle factors can reduce or increase your biological age. A 60-year-old healthy person who has eaten a lot of nutritious food, exercised regularly and refrained from bad habits like smoking can have a biological age of 50. A blood test can tell the age or biological age of a human cell, said Dr. Nanjiato-Ghobashi. If your biological age is higher than your chronological age, you can reduce this gap by making drastic changes in your lifestyle.
Depression or Anxiety: Mental health problems can be identified not only through blood tests, but also through clinical assessments. Some major neurotransmitters that control mood can be checked by blood tests, said Dr. Nanjiato-Ghobashi. One of the neurotransmitters that control mood is serotonin, which is found in the molecules and digestive tract. Low levels of serotonin can be a sign of depression or anxiety.
Risk of dementia: Whether a person suffers from Alzheimer's disease or other types of dementia depends on some risk factors. A blood test can detect the presence of chemicals that increase the risk of dementia. In particular, a protein called amyloid beta can be detected up to 20 years before dementia. A positive test does not mean that you must have dementia, it may mean that you have a high risk of dementia, says Nanjiato-Ghobashi.
Concussion: Concussion is the temporary disruption of brain activity due to a head injury. Physicians can perform neurological tests, brain imaging and close observations to find out if anyone is suffering from concussions, according to a Mayo Clinic report. A blood test can also be helpful in this case: blood tests can be done to find out if the serum electrolytes have increased, which can be an indicator of concussion, said Dr. Nanjiato-Ghobashi.
Kidney condition: After hard work or exercise, your muscles secrete creatinine - this waste product is excreted from your blood by the kidneys. If the level of stored creatinine is more than 1.2 in women and 1.4 in men, it may indicate kidney problems, according to the National Kidney Foundation of the United States. Elevated blood urea nitrogen (BUN) and very low glomerular filtration rate (GFR) can also be a sign of kidney problems. These three factors can be measured in a blood test, which can tell whether the real cause is external (such as dehydration) or internal (such as kidney stones).
Diabetes: A1C blood test will give the doctor an idea of your daily average blood sugar level and it will help diagnose diabetes. Levels between 4 and 5.6 indicate normal, but 5.6-6.4 indicates a high risk of pre-diabetes or diabetes, and 7.5 or higher indicates full-blown diabetes. Dr. Nanjiato-Ghobashi said, 'This test measures the average blood sugar of the last three months. The results of this test are more reliable than one day's blood sugar readings. That's why it can be helpful in the treatment of diabetes.
Vitamin intake: It is important to know if your body is deficient in any vitamin, because lack of vitamins can lead to various diseases. On the other hand, it is also necessary to identify whether there is an overdose of vitamins, because the presence of too many vitamins in the body can also lead to dangerous consequences. A blood test can determine the level of vitamins in the body. Dr. “Most vitamins are water soluble,” said Nanjiato-Ghobashi. This means that even if you eat a lot of these vitamins will not stay in the body for long. But because Vitamin A, Vitamin D, Vitamin E and Vitamin K are soluble in fat, they stay in the body for a long time and increase the chances of overdose. An overdose of vitamins in the body is called hypervitaminosis, which can lead to various problems, such as nausea and liver damage.
