Choosing a lab test guide is a critical part of getting a medical test performed. There are many things to consider when choosing a guide, including the type of test you'll be receiving and the location of the lab. The guide should be able to answer most of your questions, so you don't have to rely on the results of your lab test to make a decision. In addition, the guide should include all of the required information, including sample collection and process instructions. It also includes a directory of professional staff members.

In most cases, a lab test is performed on blood, as it's easily sampled and contains microscopic clues about your body. Other tests, however, may require urine, joint fluid, or a small piece of skin. Your health care provider will tell you which one will be most useful for you. The guide is intended to be a general guide, not a comprehensive guide to every test. However, it's a great start for a lab test user to get the information they need before they go to the doctor's office.
