Preparing for an Effective QFA (Quantitative Fluid Analysis)
1. Pre-Test Fasting
You must fast for 12-14 hours before taking the QFA test. If you have diabetes or any other problem with blood sugar regulation, and/or on blood sugar medication, please tell the nutritionist.
Fasting Guidelines: General Guidelines: Finish dinner no later than 7:00 pm on the night before the test. After dinner, brush your teeth and refrain from eating or drinking anything for the rest of the night and morning. If you are thirsty, you may sip a small amount of water. Do not brush you teeth, eat or drink anything in the morning until after the test. This includes: chewing gum, throat lozenges and candy, toothpaste, mouthwash or mouth rinse. No lipstick or makeup around your mouth and lips.
Dentures: If you wear dentures or orthodontic appliances, do not wear during the fasting period until after your saliva specimen has been obtained.
Sexual Activity: Refrain from sexual activity during your fasting period. This can cause false elevated readings in your urine values.
2. Urine Collection
When you wake up, void your 1st morning urine. Collect your second-morning urine, (around 7:00 am) in a clean container (supplied).
3. Saliva Collection
Start to collect your saliva sample in a clean container (supplied) about 20 minutes prior to delivery. If you are close to the office you may start the collection of saliva at home. If you are from out of town start your collection on the road.
