A CSF cell count is a test to measure the number of red and white blood cells that are in cerebrospinal fluid (CSF. CSF is a clear fluid that circulates in the space surrounding the spinal cord and brain.

This test is an analysis of cerebral spinal fluid (CSF. CSF bathes, cushions, and protects the brain and spinal cord. It flows around the skull and spine in the subarachnoid space (the area immediately surrounding the brain and spinal cord. CSF chemistry test identifies chemicals such as proteins and glucose levels, which can help diagnose certain disorders and diseases.

A cerebrospinal fluid (CSF) culture is a laboratory test to look for bacteria, fungi, and viruses in the clear fluid that moves in the space surrounding the spinal cord.

A cerebrospinal fluid (CSF) smear is a microscopic examination of the clear fluid that moves in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury.

The Gram stain test is the most extensively performed procedure in diagnostic microbiology. It is used to classify bacteria as either gram-positive or gram-negative based upon their ability to retain the crystal violet stain following decolorization.

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.

A cranial CT scan is computed tomography of the head, including the skull, brain, orbits (eye sockets), and sinuses.
|
|
|
Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).
|
|
|
CT imaging equipment includes conventional, spiral, multi-slice, and electron-beam computed tomography full-body scanners, which use x rays to acquire cross-sectional images and computer workstations to reconstruct acquired image data for display on a viewing monitor or printed on film. Also referred to as computerized axial tomography (CAT) scanning equipment.
|
|
|
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross- sectional views of body organs and tissues.

Injury to the head may damage the scalp, skull , or brain . The most important consequence of head injury is traumatic brain injury.

Lumbar puncture (LP) is the technique of using a needle to withdraw cerebrospinal fluid (CSF) from the spinal canal. CSF is the clear, watery liquid that protects the central nervous system from injury and cushions it from the surrounding bone structure.

Cerebrospinal fluid (CSF) analysis is a laboratory test to examine a sample of the fluid surrounding the brain and spinal cord. This fluid is a clear, watery liquid that protects the central nervous system from injury and cushions it from the surrounding bone structure.

FTA-ABS is a blood test is used 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 distinguishes patients with true infection from those with a false positive result of a screening test.

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 hands; Auscultation (listening to sounds; Percussion (producing sounds.
|
|
A neurological examination is an essential component of a comprehensive physical examination . It is a systematic examination that surveys the functioning of nerves delivering sensory information to the brain and caring motor commands (Peripheral nervous system) and impulses back to the brain for processing and coordinating (Central nervous system).

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.

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.

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.

|
Sexually transmitted diseases (STDs) are viral and bacterial infections passed from one person to another through sexual contact. Adolescence is a time of opportunities and risk when many health behaviors are established.
|
|
|
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. Sexually transmitted diseases are also called venereal diseases.

VDRL is a screening test for syphilis that measures antibodies that can be produced by 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 mixture of lipids such as cardiolipin, lecithin, and cholesterol) on a glass slide, and flocculation, or clumping, of the mixture is read microscopically as " reactive " (if clumping occurs) or " nonreactive " (if there is no clumping).
