Northern Virginia Pediatric Associates, P.C. is proud to have a high quality laboratory within our office building. Our laboratory is much more convenient for patients and their families as it enables your doctor to receive lab results in a more timely fashion. This allows us to quickly diagnose and treat your child. In addition, our highly qualified lab technicians are especially skilled in collecting blood and other samples from infants and small children.

In order to cover the laboratory operating costs and maintain our high quality of care, an administrative fee of $25.00 is charged for all specimens other than rapid strep and quick urine tests. Should you wish not to pay this fee, you may go to the laboratory that contracts with your insurance company. Please be aware that although your child’s specimen is collected at our office, it is sent to Quest for testing. Quest will bill your insurance for the tests and any questions regarding your Quest bill should be directed to Quest.

So that we may best serve you and limit wait time, we can no longer accommodate walk-in laboratory visits. We ask that a lab appointment be made for our patients with outside lab orders as well as those for whom a NVPA provider ordered labs to be done at a later date.  Please request an appointment through your Keona Account.

Lab Hours differ from Office Hours.  Please call before dropping off samples.

In-house testing –  M – F, 9:00 am – 12:45 pm, 2:00 pm – 4:45 pm

Quest (includes blood draws) – M – F 9:00 am – 12:30 pm, 2:00 pm – 5:00 (4:00 pm on Friday)

Instructions and Helpful Hints for Lab Tests

Please make sure your child is well hydrated (drinking water) for all blood draws.


If a fasting test is needed, your child should have nothing by mouth, except water, 12 hours prior to the blood draw.

Stool Tests

Please check with the lab for specimen requirements and specific stool collection kits that may be needed PRIOR for specimen collection. Stool not collected with a specimen kit can become contaminated such that tests cannot be performed.

AM Urine Collection

If your doctor requests an early morning urine specimen, follow instructions below:
• On the night before the examination, have child void before going to bed.
• Child should be lying down in bed.
• Urine specimen should be taken as soon as the child wakes up and brought to the lab as soon as possible.
