How can possible Age Determination by Blood Test biological age 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 microglia are measured. It can help assess a person's overall health and identify a variety of 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, issues that were caught in the blood test was discussed.

Determining age by blood |
Many people will be surprised to hear that age can be determined by blood, maybe this is science fiction? Not really. A team of scientists has recently developed a technique for determining age by blood. Once a person dies, if he is a barren corpse, the age is determined by calculating the growth of the ring in the bone. This is still being done in a country like ours. But in order to do this, it is necessary to take the initiative of surgery on the body of the dead person, which is a lot of troublesome but expensive and annoying work. But with a drop of blood from the body of any animal, not human, its age can be easily determined. A team of scientists led by Mark Hasman, a scientist at Loa State University in the United States, recently developed the method. So far they have not named any of these methods.
This method involves expanding the cell division of an animal with a drop of blood, looking for repetitive sequences at the end of chromosomes called telomerase. At this time the technique used in this work does not find the latest sequences for a good reason. It is then assumed that the telomeres have become smaller due to the age of the animals. Scientists determine the age based on the telomeres getting smaller.
During the study, the scientists studied blood from the body of a zebra finch. At the end of their test, the age of the animal was determined to be 10 years. The same results were obtained when the age of the animal was determined using other techniques. That's why scientists are convinced it is an effective method.
A team of Belgian scientists has invented an experiment to determine the age of a person based on blood or dental samples. This test will be especially useful for the police force as it will make it easier to find the culprit or identify the body.
Forensic experts can try to identify the culprit based on DNA by examining the blood sample found at the crime scene.
From now on, blood samples can also be used to determine the age of the offender. This technique also applies to the deceased. When it is not possible to determine a person's age in conventional methods, forensic experts can do so using blood or dental samples.
As we grow older, our tissues and internal organs change. This process of aging is controlled by our DNA. "The behavior of our organs and tissues depends on which genes are active," said Bram Beckert, a professor in the forensic biomedical science unit at KU Leuven University in Belgium.
As we get older, some genes start working. The rest of the work stopped. This process is partly regulated by methylation where methyl groups attach to our DNA.
Genes with high methylation levels at specific locations become inactive.
Reckert and colleagues were able to determine a person's age based on a set of four markers of methylation of age-related DNA. The methylation levels of these markers can be used very accurately in determining age.
Pregnancy status:
One of the symptoms of pregnancy is missing a period. A urine test can detect pregnancy hormone (HCG) after a period is missed. But a blood test can detect low levels of HCG, allowing a woman to know if she's pregnant before she misses her period, said Deborah-Nunziato Ghobashi, a family medicine physician at Scarsdale Medical Group.
Depression or Anxiety:
Mental health problems can be identified not only by blood tests but also by adding a clinical assessment to a person's mental state. Some major neurotransmitters that control mood can be checked by blood tests, said Dr. Nanjiato-Ghobashi. One of the neurotransmitters that regulate mood is serotonin, which is found in the microbiota 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.
Connection:
A 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 a 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:
The A1C blood test will give the doctor an idea of your daily average blood sugar level and help you diagnose diabetes. Levels between 4 and 5.6 indicate normal, but 5.8-6.4 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 blood sugar readings. That's why it can be helpful in the treatment of diabetes.
Amount of vitamins:
It is important to know if your body is deficient in any vitamin because a 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.
