Outpatient Unit

The Charles R. Drew University Clinical and Translational Research Center (CDU-CTRC) is located in a 5,000 square foot outpatient and administrative unit with seven exam/treatment rooms, a processing laboratory and a dedicated consultation space for study participant interviews. We provide cardiovascular and metabolic assessment resources, a site dedicated pharmacist, negotiated lab fees for assays, and participant transportation. Our site also offers Wi-Fi and a conference room capable of state of the art collaborative meetings for community partners and collaborators. In addition to our CTRC unit, the University offers additional conference room spaces and houses both Morphometry and Core Laboratories.

Our CTRC clinical staff is knowledgeable and skilled in protocol implementation, data collection, phlebotomy, IV insertions, pharmacokinetic studies, administration of investigational drugs, multiple sample collection, Oral Glucose Tolerance Tests, glucose clamp studies, EKGs, and assisting investigators with minor bedside procedures. Pharmacy services include procurement, disposal, packaging, randomization and dispensing. Currently CTRC services seven actively recruiting studies in the areas of HIV/AIDS, Cancer, Social/ Behavioral and Cardio-metabolic Research.

24 Hour Ambulatory Blood Pressure Monitor

24Hr ABPM monitoring provides a more accurate physiological assessment of blood pressure as compared to random blood pressure measurement obtained with the seated blood pressure method.

Quantity: 4

Models: ABPM 90207and 90217

Carotid Ultrasound Imaging

Intima Media Thickness (IMT) U/S measures arterial thickening and provides the earliest evidence of atherosclerosis, or hardening of the arteries, the beginning stage of a disease process that leads to heart disease and stroke. Doctors can use this carotid intima media thickness (CIMT) measurement to calculate the age of the patient's arteries, which does not always match the patient's calendar age.

Quantity: 1

Model: M-Turbo

Exercise Physiology Laboratory

A 3,000 square foot Exercise Physiology Lab is located in the ERC Business Park approximately one mile from KDMC. It is fully equipped with Keiser pneumatic resistance training equipment, free weights, treadmills, stationary exercise cycles, as well as state-of-the-art, computerized equipment for measuring muscle performance, cardiopulmonary response, and body composition. These tools are available for utilization by investigators working the field of health disparities related to endocrine metabolism and exercise physiology. For additional information, please contact
Humberto Sanchez, Exercise Technician, 323-249-5715, humbertosanchez@cdrewu.edu

Mobile Clinical Protocol Services

This service will allow study participants the opportunity to continue to participate while temporarily unable to visit the CTRC due to conditions not related to study protocol exclusion criteria. All study participants utilizing Mobile Clinical Protocol Services must be enrolled in current/ approved IRB study protocols. This program is dedicated to furthering research and providing dedicated ancillary support.

Services Include: (but not limited to)

Point of Care Testing (CLIA Waived -HA1c, Urine Dips, etc.)
Blood Pressure Measurement (including 24hr monitoring)
Anthropometric Measurements
SpygmoCor (Pulse Wave Velocity/Pulse Wave Analysis)
EndoPat (Endothelial Function)

Bone Density and DXA Analysis (Body Composition)

Bone density and body composition by DXA (Dual Energy X-Ray Absorptiometry) is considered the "gold standard" for osteoporosis and body fat testing. Accurate measurement is important in assessing health. These exams are non-invasive and take roughly 15-30 minutes to complete.

Glucose Clamp Test

CLAMP test measures how the body responds to insulin. Subjects fast the night before each test and do not eat until the test is over, usually in the early afternoon. For the test, the subject lies in a bed or reclines in a chair. An intravenous access is placed in a vein in each arm - one for collecting blood samples and the other for infusing glucose and insulin. Blood glucose is measured frequently during the test and the rate of the glucose infusion is adjusted to keep blood glucose at the baseline (fasting) level. Insulin levels are measured at timed intervals via plasma aliquots.

Specimen Preparation

Organizing and processing various specimens for contracted, local and/or core laboratories.


Participants are provided with one-way or round-trip transportation to the CTRC for study protocol visits.

Pharmacy Services

Medication Dispensing
Drug preparation, packaging, and labeling. Facilitating medication distribution, storage, security and documentation.

Medication Procurement
The complete action or process of acquiring or obtaining drugs from an outside pharmaceutical company. More specifically, the action or process of purchasing, contracting, and negotiating directly with the source of supply.

Subject Randomization
A process that assigns research participants by chance, rather than by choice, to either the investigational group or the control group.Single-blinded trials are those in which participants do not know which group they are in and therefore which intervention they are receiving - until the conclusion of the study.
Double-blinded trials are those in which neither the participant nor the investigators know to which group the participant has been assigned until the conclusion of the study.

Medication Waste Disposal
The destruction of unused or expired drugs in accordance with federal and HIPPA guidelines.

Contract Laboratories

Negotiated non-profit fee schedule
