Labs, Imaging & Other Testing


The drawing center is open to meet your laboratory needs from 8:00am to 3:50pm Monday to Friday. A lab appointment is required. Please schedule your lab appointment here. Our busiest times are from 8:00am – 11:00am. We do request your patience as there can be a large volume of patients to be assisted.

About the Lab:

  • Most laboratory testing is done on-site, however, sometimes samples need to be sent to a reference lab, for clinical reasons as well as issues of insurance coverage. Even though your specimen is collected here, we will make sure that the correct reference lab receives the specimen, and that your physician receives the results.
  • Your orders can be transmitted electronically to either LabCorp or Quest if required by your insurance. Please note that it takes approximately 24 hours for orders to transmit.
  • There is a charge of $50 to draw kits at our draw center.
  • If you do not receive your results from your provider within 10 business days please contact the office at 301.762.5020.
  • The Rockville Internal Medicine Clinical Laboratory is open Monday through Friday from 8:00am – 4:00pm.
  • All laboratory tests must be ordered by your physician. If the orders for your tests have not been placed in advance, we will need to contact your physician for an order and this might lengthen the wait time. Pre-Op lab orders cannot be collected unless the patient has been seen by the PCP first.
  • Do not eat 8 hours before your blood test if you are having tests that require you to fast (physicals, lipids, diabetes, etc.). However, make sure you drink plenty of water. Do not stop taking your medication unless otherwise instructed by your provider.
  • Lab orders more than twelve (12) months old cannot be honored.
  • The CLIA certified lab is staffed with certified Medical Lab Scientists for processing lab tests.

Important Reminders:

  • Practice social distance while waiting.
  • Urine samples must be collected in the sterile container provided by the lab. Specimens not collected properly will be discarded.
  • Stool specimens must be transferred to the appropriate containers prior to returning to the lab for testing. Please follow the instructions provided.
  • All patients need to check in at the lab reception desk, even if only picking up a 24-hour urine container or stool kits.
  • Average wait time is 15-20 minutes following check in and can increase or decrease based on patient volume.
  • Lab appointments can be scheduled here.
  • All drop-off urine and stool specimens must be received by 3:00pm, Monday – Friday.
  • Patients cannot get lab results at the draw center. Results must be requested at the main reception desk.

To determine your risk of developing osteoporosis, Rockville Internal Medicine has available Dual Energy X-Ray Absorptiometry (DEXA scanning). This test evaluates your bone density level and can be used to assess your risk for fractures.

Pulmonary Function Lab

A cough and shortness of breath are troubling symptoms that sometimes indicate the presence of a serious underlying condition. In order to diagnose and treat these conditions, the pulmonary physicians at Rockville Internal Medicine Group have developed a state of the art Pulmonary Function Lab. By performing these tests, your physician can determine lung functions as simple as how forcefully you can blow air out, or as sophisticated as for how efficiently your lungs extract oxygen from the air. This testing, as well as X-ray and endoscopic evaluations when necessary, will help your physician determine the cause of your symptoms. Once that is determined, your physician can direct you to therapies to preserve and restore your health. Hours of operation are Tuesdays thru Fridays from 8:00am to 4:00pm.
