Answer by  John (9008)

There are hundreds of different blood tests that doctors can order. Common tests include for diseases, cholesterol, liver enzymes, and more. Blood tests are a standard part of any thorough physical, and nothing about which to worry.

That depends entirely on the reason the test was taken. There are a variety of things which can be found from testing blood, however doctors are only likely to test for something specific.

They can look at all kinds of things in a blood sample: blood sugar levels, amounts of various hormones or salts and proteins that can indicate potential diseases or problems. They may also be looking at your red cell/white cell/plasma count, which can be indicative of other conditions. You should ask your doctor why the test was needed.
