It explains the most important indicators to pay attention to, and common mistakes that may distort the diagnostic results
A sharp rise or fall in blood sugar levels is one of the most dangerous indicators. He says, "Values above 20 mmol/L or below 3 mmol/L may indicate a risk of diabetic coma. Even in people without diabetes, glucose levels can fluctuate during severe stress, poisoning, or acute illness."
A level below 70 g/L indicates severe anemia, meaning that tissues and organs are not receiving enough oxygen, which is dangerous for the heart and brain. The patient may experience weakness, shortness of breath, and dizziness, but sometimes there are no noticeable symptoms at all.
These cells are responsible for blood clotting. An increase in their number (500–800 billion/L) increases the risk of blood clots and blockage of blood vessels, while a severe decrease in their number (less than 150 billion/L) increases the likelihood of bleeding, even from minor injuries.
creatinine:This indicator reflects kidney function. Elevated levels may indicate a reduced ability of the kidneys to filter waste products, even in the early stages of the disease, when a person may not notice any health problems. A level of 110–150 µmol/L may indicate early kidney dysfunction requiring further evaluation.
This test measures the body's iron stores. Low levels (less than 15–30 ng/ml) are often associated with anemia and persistent fatigue, while high levels (more than 400 ng/ml) may indicate underlying inflammation or excess iron in the body.
The expert emphasizes that abnormal test results are not always a sign of illness; they may be caused by errors in test preparation. Some of the most common of these errors include:
Strenuous exercise 12–24 hours before taking the sample stresses the body and raises the levels of creatine kinase, AST, LDH, C-reactive protein, and white blood cells, which may resemble myocarditis, myopathy, or dehydration.
Consuming alcohol the day before the test is prohibited because it affects glucose, triglyceride, and liver enzyme levels, and may cause a decrease or increase in blood sugar, and changes the volume of blood plasma, which distorts the results of biochemical analyses.
It is necessary to perform glucose and triglyceride tests on an empty stomach (8–10 hours after the last meal), while a light meal may be eaten before a general blood test or to determine antibodies or hormone levels.
