Answer:
Blood tests help doctors check for certain diseases and conditions. They also help check the function of your organs and show how well treatments are working. Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working.
Explanation:
Blood tests show whether the levels of different substances in your blood fall within a normal range.
• For many blood substances, the normal range is the range of levels seen in 95 percent of healthy people in a certain group. For many tests, normal ranges vary depending on a person’s age, gender, race, and other factors.
• Blood test results may fall outside the normal range for many reasons. Abnormal results a disorder or disease.
So, doctors prefer to go for a blood test before diagnosing any disease. Complete Blood Picture (CBP) gives the ample information about the patient and helps in diagnosing the disease.
For example: The ranges for blood glucose levels after 8 to 12 hours of fasting (not eating) has a certain range for a normal person. If it shows abnormal ranges than that is a sign of pre-diabetes or diabetes.
