Most of our diagnostic testing is performed using our on-site accredited clinical laboratory, which is open for all studies from 8:00 AM until 4:30 PM on weekdays.

Here we perform blood tests, urinalysis, electrocardiograms,  and strep throat tests, generally on a “walk-in” basis. If any imaging studies are necessary, such as  X-rays, ultrasound, CT, or MRI exams, we generally utilize providers of these services in the Foxhall Square building, or at one of the local hospitals.

Most tests do not require any specific preparation. However, if you have been asked to fast prior to your test, such as for a check of your cholesterol or as part of a routine physical examination, please do not eat for eight to twelve hours prior to arriving. It is advisable to drink water on the morning of any blood testing, since drawing blood can be more difficult if you are dehydrated. You may take your medicines according to their usual schedule, unless you have been advised otherwise.

In addition to the above tests, we also offer:

Ambulatory Blood Pressure Monitoring
This is done either to ensure that patients with hypertension have satisfactory control of their blood pressure with medication, or to determine if patients have “white coat hypertension,” in which blood pressure is high in our office but otherwise normal. A small monitor records blood pressure readings for 24 hours, and the data are then analyzed by your physician.

Bone Densitometry (DEXA scan)
Screening for osteoporosis is now routinely performed in our office, with the goal of detecting a decrease in bone density before there is a fracture. If your bone density is found to be lower than it should be, a number of medications are available which either reduce the chance of further bone loss, or in some cases help to rebuild bone. Further details on this test can be found on this site by clicking here.

Holter Monitoring
Often patients who experience palpitations (sensations of an irregular heart rhythm) have no unusual findings when their heart is examined, and have a normal electrocardiogram. A Holter monitor is used in this situation to determine why the palpitations are occurring. Every heartbeat is recorded for 24 hours, and the information is then used to determine what is causing the palpitations, and whether any further treatment is necessary. Holter monitoring can also be used for evaluation of recurrent dizziness if a heart problem is suspected, and for assessing how well medication is working to control abnormal heart rhythms.

Laboratory Accreditation 

Foxhall Internists has once again met all criteria for Laboratory Accreditation by COLA, a national healthcare accreditation organization. Accreditation is given only to laboratories that apply rigid standards of quality in day-to-day operations, demonstrate continued accuracy in the performance of proficiency testing, and pass a rigorous on-site laboratory survey. Foxhall Internists has routinely earned COLA accreditation in its biennial surveys as a result of their long-term commitment to provide quality service to its patients.
