What do blood tests inform us?

Blood tests are one of the most important procedures that doctors regularly prescribe. But what is their purpose and what information can be obtained from the test results?

Before making a diagnosis, a doctor needs to conduct a blood test. Blood is usually taken from a finger or a vein, and this is often done on an empty stomach.

Among the most common types of blood tests are: a complete blood count, a biochemical analysis, a hormone test, and tests for trace elements and vitamins.

What does a complete blood count show?

A complete blood count gives a comprehensive picture of your health. Based on its results, a doctor can evaluate the number of white blood cells, blood coagulation, and identify the presence of inflammatory or infectious processes in the body.

For example, the normal erythrocyte sedimentation rate (ESR) is 15 mm/h. An increase in this indicator may signal the onset of an inflammatory process.

What does a biochemical blood test show?

A biochemical blood test allows the evaluation of the state of organs such as the liver, kidneys, pancreas, and the cardiovascular system.

The blood sugar level, which is determined during a biochemical analysis, is an indicator of the condition of the pancreas. A value of up to 5.5 mmol/L is considered normal. Exceeding this level may warrant a visit to an endocrinologist, as high sugar levels can lead to diabetes.

Additionally, a biochemical analysis determines the level of hemoglobin, which is normally in the range of 120-160 g/L. The cholesterol level, which is also measured during this test, should not exceed 5 mmol/L.

Vitamin Blood Test

Despite the abundance of products on store shelves, vitamin deficiency remains a common issue.

Many people start taking vitamin complexes; however, excessive consumption of vitamins can be just as dangerous as their deficiency.

It is recommended to check vitamin levels in the body once a year by taking a blood test for vitamins.

Trace Element Blood Test

This test determines the levels of trace elements such as calcium, potassium, sodium, chlorine, iron, zinc, magnesium, and iodine.

Each of these elements plays an important role in the functioning of the body. For example, potassium is necessary for the normal functioning of the heart, zinc is important for skin health, and magnesium is essential for nerve signal transmission. Calcium is responsible for bone and dental health, sodium regulates water balance, chlorine maintains acid-base balance, and iron affects oxygen levels in the blood.

Medical professionals advise taking a trace element blood test at least once a year, even for healthy individuals. For those who are ill, this is especially important, as restoring levels of essential trace elements can aid in recovery.

Hormone Blood Test: What Will It Show?

Hormones play a key role in our bodies. Disruption of hormonal balance can negatively affect the quality of life.

If you are experiencing nervous disorders, weight gain that does not respond to diets, difficulties with conception, or skin problems such as acne, this may be a reason to check hormone levels in your blood.

The laboratory analyzes blood for thyroid hormones and sex hormones.

Important! It is not recommended to consume iodine and iodine-containing products (for example, seaweed) 7 days before undergoing a hormone blood test.
