Patient request for laboratory results

Blood tests are used to diagnose and monitor treatment for a variety of conditions. Northwell Health Labs makes getting blood drawn easy with services at all our patient service centers. Before visiting one of our conveniently located locations for blood drawing:

  • Call your physician or the Northwell Health Labs location nearest you to determine if tests ordered will require fasting or special preparation.
  • Be sure to bring a copy of your physician’s test requisition or prescription along with your insurance information or card.
  • Appointments are only necessary for time-sensitive tests such as glucose tolerance and platelet aggregation.

Our experienced phlebotomists are also trained in pediatric care and will use calm and gentle techniques to make sure your child feels as comfortable as possible. Ask for a copy of our Parent’s Guide for some helpful tips for you and your child.

Your physician will receive a completed report from Northwell Health Labs when your test results become available.

If you do not have your insurance card, we will still draw your blood. However, you will have to follow-up by faxing a copy of your insurance information directly to our Billing Department at (516) 414-3825. We accept all major insurances. We also accept payment via cash, check or credit card.

Translation services are available in more than 180 languages. Ask the phlebotomist for assistance.
