Common Questions

Do I need an appointment?

Most laboratory testing does not require that you make an appointment. Generally if an appointment is necessary, your physician's office will call and make one for you.

Examples of tests that do require an appointment are:

  • 2 or 3 Hour Glucose Tolerance Tests
  • Sweat Chloride Tests
  • Cortisol Stimulation
  • H. Pylori Breath Test

All testing requires an order from your physician.

Do I need to be fasting?

Tests that are affected by your diet such as blood sugar or lipids (Triglyceride, Cholesterol) generally require that you have nothing to eat or drink after midnight of the night prior to the morning of having your blood drawn.

It is usually allowable for you take any prescription medications with a small amount of water. Usually your physician's office will let you know if you need to be fasting or if any other special preparations need to be made for any of your testing.

If you are not sure, please check with your physician's office.

Where do I go to get my blood drawn?

If your provider has requested that your tests be evaluated immediately, the results will sent to your doctor's office as soon as they are complete via fax or remote printing

How I get my pathology slides for consult

A patient can have their pathology slides sent out for a second opinion and this can be accomplished in two ways:

  1. The patient can contact their physician and ask for their slides to be sent out for a second opinion. The patient can suggest where to send the slides or ask the physician for a reference. The physician's office will contact the Pathology Dept. at Rex and request that the patient's slides be sent for a second opinion and provide Pathology with the appropriate information. (Preferred Process)
  2. The patient themselves can contact the Pathology Dept. at Rex (784-3072) and request that their slides be sent for a second opinion. It is our preference that the patient provide the necessary information of the institution they desire to receive the pathology slides, however, we can have the pathologist suggest a reference at the request of the patient.

General Information:

  1. In the above scenarios, the patient will be responsible for all cost associated with the consultation from the second institution. Rex will forward current patient billing information if available to the second institution. If the current information is not available, it will be the responsibility of the patient to provide the current billing information.
  2. We request that the patient give us a week to prepare the slide(s), report(s), and letter to be sent to the institution receiving the request for consultation. Many of our older pathology cases are stored off site and require more time to obtain and prepare.
  3. In order to expedite the send out process, the person requesting the second opinion should have all of the following information: patient name at the time of surgery, date of birth, date of surgery, type of surgery, specific information of who to send the request to including address and telephone number, and date needed by.
