Thank you for your question, and I am sorry to hear about your anxiety

. An HIV test (for human immuno deficiency virus) is not generally ordered without the consent of the patient except in certain situations that are closely regulated in the United States. At the same time, there are obvious advantages (and, some would argue, disadvantages) to knowing your HIV status, and so employers and health care providers will sometimes offer patients the opportunity to be tested. At times, this information can be useful to establish if an employee was infected by exposure on the job or was already infected, which may affect insurance coverage thereafter. It is common for testing to occur in a 2 stage pattern, with the first test being a good screening test, which is then followed by a more exact test only if the first test is positive. This is an effective and less expensive way to determine if a person in the general population has contracted the virus. Fortunately, in most situations, you are in control of the testing and how it is handled. If you are having concerns about understanding the questions that are being asked of you, and with this question in general, please speak with your doctor.
