What Are Blood Tests and How Do They Help Diagnose Health Conditions?
Blood tests provide essential information that can help doctors diagnose medical conditions and diseases. These tests, which measure the level of various substances in the body, can detect diseases early on and help gauge how they are progressing. Knowing which type of tests are necessary and what they can tell you is essential in keeping your health in check.
Types of Blood Tests
Blood tests can measure a variety of things, including complete blood count (CBC), electrolytes, hormones, cholesterol levels, sugar levels (blood glucose) levels and kidney and liver function tests. Depending on what your doctor suspects and the symptoms you are exhibiting, he/she will choose which tests to conduct.
How Blood Tests Help in Diagnosing Health Conditions
By looking at the levels of various substances in your blood sample, it is possible to determine if there are any underlying health conditions that need to be addressed. For example, blood glucose levels help diagnose diabetes, whereas electrolytes show if you have any dehydration or an electrolyte balance issue. Similarly, liver and kidney function tests help to detect any underlying conditions such as chronic kidney disease or conditions like hepatitis.
Are There Risks Associated with Blood Tests?
Blood tests are generally considered to be a safe procedure, and the risks associated with the tests are extremely low. The most common risk associated with blood tests is the risk of infection, which can be easily minimized by using sterile needles and following good hand hygiene. It is important to keep in mind that some blood tests are more invasive than others and may require special precautions.
