For Providers

Children’s National offers walk-in pediatric lab services at multiple locations — no appointment needed. To refer a patient, simply provide the family with a hard copy of the lab order that includes all appropriate diagnosis codes to help avoid processing delays. 

Why Refer to Children’s National Lab Services? 

• Pediatric-trained staff: All lab services are staffed by professionals with specialized training in working with children, including those with special needs. 
• Walk-in access: No appointment is necessary — families can visit at their convenience during posted hours. 
• Family-friendly care: Our labs are designed to reduce fear and stress, making the experience more comfortable for kids. 
• Streamlined workflow for providers: We handle lab work efficiently and compassionately, easing administrative demands on your practice.
• Integrated results: Lab results are delivered through the Children’s National Provider Portal and faxed to the number provided on the lab order. 

Important Reminders

• Please include all necessary diagnosis codes on lab orders to avoid delays. 
• Even when processed by an external reference lab, results are uploaded to our portal — not to your reference lab account(s). 
• For hours and locations, visit our Blood Draw Services page. 
• Unless it is an emergency, please do not direct families to the Emergency Department for routine blood draws.
