Preparing for Your Test

Before a laboratory test, a physician must go over test preparations with a patient. Follow all physician guidelines pertaining to abstaining from substances and activities.

Platinum Diagnostic Lab technicians will administer the test on your specified test day. Prepare accordingly and refrain from specified activities or from using or ingesting certain substances, as indicated by your physician.

Below are standard preparation procedures for common tests. Only use these as a guide and always thoroughly follow your physician’s instructions.

 

Preparing for your lab test

Tips for a simple, accurate laboratory test:

  • Cholesterol and glucose tests typically require an 8-hour fast period prior to blood sample drawing. Do not drink or eat anything. Water is allowed.
  • To prevent dizziness and fainting, drink plenty of water prior to a blood drawing.
  • If your physician does not require fasting prior to your test, eat breakfast to prevent lightheadedness. However, do not eat directly before the test; a full stomach during blood drawing may cause nausea.
  • Unless otherwise specified by a physician, continue taking your regular medications.
  • Alert your Platinum Diagnostic Lab technician if you take blood thinners.
  • Relax prior to, and during the test. Ask questions if you feel uneasy.
  • Eating a snack and drinking fluids is encouraged immediately after the sample has been drawn.
  • You may remove your bandage after an hour. If you notice any bleeding, apply light pressure to the area and secure a new bandage. Bruising is normal.

24-hour Urine Sample


Refrain from the following 8-12 hours prior to your 24-hour urine sample:

  • Smoking
  • Coffee
  • Tea
  • Vigorous exercise

Do not use your first morning urine. Collect a sample each time you urinate after the initial morning urine. Refrigerate your urine container until it is submitted. Remember to write your name, date, and time on each sample container.

Before a blood test, it is typically required you fast starting at midnight the night before. Liquids including water, black tea and black coffee are okay to drink; but, refrain from sugar and dairy. Continue to take your regular medications unless your physician tells you otherwise.

 

Fasting is required for the following tests:

  • Lipid
  • Glucose testing
  • Vitamin K

Stool Analysis

Digestive track conditions are often tested with a stool sample. Acceptable containers for a stool sample are thoroughly-cleaned milk jugs or stool collection hats, also referred to as “firemen’s hats.”

Containers should be filled to the indicator line. Write your name, date, and time on your stool collection container.
