What do doctors look for in a blood test?

I had to have blood drawn this morning for a blood test, and have no idea what they are looking for.

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.
