Lab Results – What they all mean!

When you screen and do a study, you will have many procedures done to determine if you are healthy.  Here are some of the most common tests done with links for additional information primarily through wikipedia.  I’m working on this!  Please note that any information provided is not to be used as medical advice!

Basically the genetic makeup of a person.  Drug companies may add this test in order to determine why some people react to a drug in a particular way when others don’t. 

 

The test is usually one tube of blood.
Human immunodeficiency virus (HIV) is a virus that can lead to acquired immunodeficiency syndrome (AIDS).  All clinics will screen for HIV and AIDS.  These tests must be negative for you to participate in a healthy Phase 1 trial. 

 

The test is done via blood sample.
Electrocardiogram (ECG/EKG) is a test that measures the electrical activity of the heart.

The test is done using an ECG machine with 10 to 12 leads attached to your chest and limbs via sticky pads.

 

Vitals signs measures your blood pressure (systolic and diastolic), body temperaturepulse rate and respirations.

 

Hepatitis AB and C

The test is done with a blood pressure machine and temperature probe. Respirations are counted manually.

Hepatitis is an inflammatory virus of the liver. It is divided into several categories but the main 3 are A, B and C. Most clinics only test for B and C. If you have had a vaccination for either of the infections, you should inform the clinic of when the vaccination was done. Some studies will not allow subjects with certain vaccinations.

The test is done via blood sample.

 

BMI/IBW 
Body Mass Index Calculator/Ideal Body Weight Calculator.  Some studies use the BMI scale while others use the IBW scale.

 

A Urinalysis (UA) tests for illicit drugs, alcoholcotinine and other factors.

 

Drugs:

 

Alcohol
Amphetamine
Barbiturates

The test is done with approximately 40 ML of urine collected into a sterile specimen container.

 

Having your blood drawn (phlebotomy) is the primary source of information that is collected during a study.mThe following is a list of general tests that are usually done.  There may be additional tests done for study specific requirements.

The test is typically done using a needle with a barrel and vacutainers. The needle is inserted into a vein and the required amount of tubes are inserted one at a time. Once the tubes are filled, the needle is removed and gauze is placed over the hole. Hold the gauze with firm pressure for 5 to 10 minutes or until the hole is sealed and has stopped bleeding.
