Tests could include:
 |
Serum VDRL or serum RPR (used as screening tests). If these are positive, one of the following will need to be done to confirm the diagnosis: FTA-ABS; MHA-TP;
|
|
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with ha...

The health status of populations and of individuals is assessed for many reasons. Assessing needs for care helps guide the allocation of resources— diagnostic assessments guide treatment, prognostic assessments contribute to planning, and assessin...

The VDRL test is a screening test for syphilis. It measures substances, called antibodies, that can be produced in response to Treponema pallidum, the bacteria that causes syphilis. The test is similar to the newer rapid plasma reagin (RPR) test.
|
|
In connection with syphilis control, the standard test for measuring nontreponemal antibodies is the Venereal Disease Research Laboratory (VDRL) test. In this test, heated serum or unheated cerebrospinal fluid is mixed with reagin (a purified mixt...

|
|
The FTA-ABS test is a blood test to detect antibodies to the bacteria Treponema pallidum, which causes syphilis. This test is used to confirm whether a positive screening test for syphilis means there is a true infection.
|
|
The fluorescent treponemal antibody absorption (FTA-ABS) test measures a specific antibody made against Treponema pallidum , the bacterium that causes syphilis. The test is reserved for confirmation of a positive screening test for syphilis and di...

RPR (rapid plasma reagin) is a screening test for syphilis. It looks for antibodies that are present in the blood of people who have the disease. The test is similar to the venereal disease research laboratory (VDRL) test.
|
|
The rapid plasma reagin (RPR) test has several useful purposes. It is used to screen asymptomatic individuals for syphilis, diagnose symptomatic infection, and monitor disease activity and response to treatment. Unlike the fluorescent treponemal a...

Sexually transmitted diseases (STDs) are caused by a group of infectious microorganisms that are transmitted mainly through sexual activity. These agents represent a costly, burdensome global public health problem. STDs can cause harmful, often ir...

Viral and bacterial infections passed from one person to another through sexual contact. Adolescence is the period of transition from childhood to adulthood when profound changes occur. This period of tremendous change fulfills important developme...

Sexually transmitted diseases (STDs) are viral and bacterial infections passed from one person to another through sexual contact.
|
 |
Sexually transmitted disease (STD) is a term used to describe more than 20 different infections that are transmitted through exchange of semen, blood, and other body fluids; or by direct contact with the affected body areas of people with STDs. Se...

A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; T...

 |
One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (...
|
|
The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the "complete blood count" (CBC). It is used commonly to assess whether a patient is anemic (low r...

|
A blood culture is a laboratory test to check for bacteria or other microorganisms in a blood sample. Most cultures check for bacteria. A culture may be done using a sample of blood, tissue, stool, urine, or other fluid from the body. See also: Br...
|
|
A blood culture is done when a person has symptoms of a blood infection, also called bacteremia . Blood is drawn from the person one or more times and is tested in a laboratory to find and identify any microorganism present and growing in the bloo...
|
|
A blood culture is a lab test designed to detect the presence of bacteria , yeast, or fungi in the bloodstream. A routine blood culture involves injecting a sample of the patient's blood into two bottles of sterile nutrient broth (one for aerobes ...
|
|
Fever evaluation tests, better known as febrile agglutinins tests, are performed to detect the presence of antibodies in the blood that are sensitive to temperature changes. Antibodies are proteins produced by the immune system in response to spec...
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom...
|
|
Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum . Tests for syphilis can be either treponemal (identifying an antibody that occurs specifically in T. pallidum infection ) or nontreponemal (identifying a ...

|
ESR stands for erythrocyte sedimentation rate. It is a test that indirectly measures how much inflammation is in the body. However, it rarely leads directly to a specific diagnosis.
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.
|
 |
The blood differential test measures the percentage of each type of white blood cell (WBC) that you have in your blood. It also reveals if there are any abnormal or immature cells. See also: Complete blood count (CBC; Eosinophil count - absolute.

A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet co...
