Common Diagnostic Tests and Instructions:

Fasting Blood Sample Preparation

Do not eat any food or drink any liquids (except for water) for 10 to 12 hours before the exam. Typical examples of tests that require fasting are metabolic panels, lipid panels that test cholesterol levels, and glucose tests that measure the amount of sugar present in your blood. The glucose test is a common way to diagnose and monitor diabetes.

H.pylori stool antigen is another test that may require fasting for several hours before completing it. Please return the stool sample to the laboratory within 24 hours for a H.pylori stool antigen test.

For the following tests, please pick up a collection container from one of the WMHS laboratory locations:

Routine Urine Collection

Try to collect the first urine of the morning for a single routine urine collection. This is the strongest and most concentrated and often provides the clearest results. When preparing to give a urine sample, place soap and water on a cloth or use a separate moist towelette to clean the skin surrounding the genital area. This ensures the sample is not contaminated. Allow the first few drops of urine to fall into the toilet bowl. Place the collection cup underneath the steady stream to catch the remaining amount. Secure the lid on the collection cup, close it tightly, and return it to a laboratory location.

Stool Cultures

A single stool sample can provide enough specimens for multiple tests like a stool culture, occult blood, fecal white blood count (WBC), ova and parasites, and Clostridium difficile (c.diff). Dietary restrictions are not necessary when collecting these types of stool specimens.

Begin a stool sample collection by eliminating directly into the stool collection container and provide as much as the container can hold. Let the remainder fall into the toilet. Use a separate stool collection container for each stool sample. Be sure to collect each sample no more than 24 hours apart. Label the stool collection container with your name, date of birth, and the date and time of collection. Do not refrigerate the stool sample(s) or mix them with urine or water prior to bringing them to the laboratory. Return a stool culture to the WMHS laboratory within one hour of collection.

4-Hour Urine Collection

For a 24-hour urine collection, do not start with the first-morning urine on day one. Collect every urine specimen throughout day one, finishing with the first-morning urine the next day. The timing and volume of the urine samples are critical for this test. Collect all urine throughout the day within the time intervals that your doctor provided. After collecting a sample, place it in the refrigerator. Collect all samples for every interval and deliver all samples to the laboratory at the time of your appointment.

Receiving Your Results

WMHS laboratory technicians will interpret results the same day as the sample is received and provide a written report to your doctor. Your doctor will follow up with you regarding the results. Depending on the results, your doctor may discuss a diagnosis and treatment options.
