Types of Blood Tests and What They Test For

  • Complete Blood Count (CBC): This blood test measures your red and white blood cells, as well as your platelets. It can help determine if you have anemia, leukemia, or other blood diseases.
  • Chemistry panel: This test measures levels of electrolytes, proteins, enzymes, and other substances such as cholesterol and glucose (blood sugar) in the blood, which can be indicators of liver or kidney function.
  • Blood Culture: This blood test is used to identify bacteria, fungi, and viruses in the bloodstream and help diagnose any possible infections.
  • Thyroid Test: This blood test measures the thyroid stimulating hormone (TSH) level in the blood, which can measure thyroid function. High or low levels of TSH may indicate an overactive or underactive thyroid.

What to Expect During a Blood Test

A blood test is typically a quick procedure that requires minimal preparation. Depending on the type of blood test, a doctor or nurse will collect a sample from your arm or hand by inserting a small needle or syringe and taking a sample of your blood. The sample will be sent for lab analysis.

Understanding Your Blood Test Results

It is important to understand the results of your blood test to help monitor your health. Your doctor can interpret the results and help explain any abnormal levels, or provide you with further advice on any health concerns. Remember to always speak to a healthcare provider if you have any questions or concerns about your blood test results.


Overall, blood tests are an important tool for understanding the health of your body, and can help identify any potential issues. By understanding what to expect during a blood test, as well as how to interpret the results, you can be more informed in making decisions about your health.
