Please follow your practitioner’s instructions before having your blood drawn. Your practitioner may require you to do certain things prior to your blood draw, have it drawn at a certain time of day, or after a certain medication is taken. Following your practitioner’s instructions will insure that your blood results will be the most accurate for diagnosing your symptoms.
One of the most common requests of a patient is fasting before their Blood Draw. Fasting for a blood test entails avoiding all food and beverages (except for water) for 8 to 12 hours prior to the test.
The second most common request is that a patient drink plenty of water and take their medications as usual. Drinking water before your blood draw will help make your veins more accessible.
In addition to these preparations, making sure you are warm, or asking for a heating pad for your arm will help to relax your blood vessels, making them easy to access. If possible, gentle activity prior to your appointment can also help open the blood vessels. However, extreme activity can sometimes alter the results of certain tests.
Note: A small number of tests have stricter requirements which involve consuming nothing, including water, for one hour prior to the test.
If you have anxiety about Blood Draws please let your practitioners know and they will help guide you in the appropriate direction prior to your appointment to make this an easy process for you.
