Blood tests will be done to rule out other infections and help confirm meningococcemia. Such tests may include: Blood culture; Complete blood count with differential; Clotting studies (PT, PTT. Other tests that may be done include: Lumbar puncture...

Meningococcemia is the presence of meningococcus in the bloodstream. Meningococcus, a bacteria formally called Neisseria meningitidis , can be one of the most dramatic and rapidly fatal of all infectious diseases.

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.
|
|
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: Bronchoscopic culture; CSF culture; Endocervix culture; Fecal culture; Throat swab culture; Urethral discharge culture; Urine culture.
|
|
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 blood.
|
 |
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 and one for anaerobes), incubating the bottles at 35DEGTAGC, and monitoring the bottles for growth over a period of five days.
|
|
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 specific infectious agents, such as viruses or bateria.

Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than x-ray image and involves no radiation exposure.
|
 |
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart ' s valves and chambers as well as the flow of blood through the heart.
|
|
An echocardiogram (echo) is an imaging test. It helps your doctor evaluate your heart. Here is how it works.

|
|
Echocardiography is a diagnostic test that uses ultrasound waves to produce an image of the heart muscle and the heart ' s valves. Purpose Echocardiography is used to diagnose certain cardiovascular diseases, and is one of the most widely used diagnostic tests for heart disease.

 |
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
|
 |
A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest area.

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.

|
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.
|
|
Partial thromboplastin time (PTT) is a blood test that looks at how long it takes for blood to clot. It can help tell if you have bleeding or clotting problems.
|
|
The partial thromboplastin time (PTT) test is a blood test that is done to investigate bleeding disorders and to monitor patients taking an anticlotting drug (heparin). Purpose Diagnosis Blood clotting (coagulation) depends on the action of substances in the blood called clotting factors.
|
|
Prothrombin time (PT) is a blood test that measures the time it takes for the liquid portion (plasma) of your blood to clot. See also: Partial thromboplastin time (PTT)
|
 |
The prothrombin time test belongs to a group of blood tests that assess the clotting ability of blood. The test is also known as the pro time or PT test.
|
|
Hemostasis has been described as "a process by which the body spontaneously stops bleeding and maintains blood in the fluid state within the vascular compartment." There are at least four major systems that are involved in this complex process: the vasculature system, the platelets, the fibrin-forming system, and the fibrin- lysing system.

|
A skin lesion biopsy is the removal of a piece of skin to diagnose or rule out an illness.
|
|
A skin biopsy is a procedure in which a small piece of living skin is removed from the body for examination, usually under a microscope, to establish a precise diagnosis. Skin biopsies are usually brief, straightforward procedures performed by a skin specialist (dermatologist) or family physician.

Urinalysis is the physical, chemical, and microscopic examination of urine. It involves a number of tests to detect and measure various compounds that pass through the urine.
|
|
Urinalysis is a diagnostic physical, chemical, and microscopic examination of a urine sample (specimen). Specimens can be obtained by normal emptying of the bladder (voiding) or by a hospital procedure called catheterization.
|
|
A urinalysis is a group of manual and/or automated qualitative and semi-quantitative tests performed on a urine sample. A routine urinalysis usually includes the following tests: color, transparency, specific gravity, pH, protein, glucose, ketones, blood, bilirubin, nitrite, urobilinogen, and leukocyte esterase.
|
|
Urinalysis is an important test used in diagnosing diseases of the genitourinary tract. Urine is examined for pH and specific gravity by chemical and direct microscopic methods.
|
|
Urine typically contains epithelial cells shed from the urinary tract. Urine cytology evaluates this urinary sediment for the presence of cancerous cells from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.

A urinalysis is a group of manual and/or automated qualitative and semi-quantitative tests performed on a urine sample. A routine urinalysis usually includes the following tests: color, transparency, specific gravity, pH, protein, glucose, ketones, blood , bilirubin, nitrite, urobilinogen, and leukocyte esterase.
|
|
The urine specimen collection is a procedure used to obtain a sample of urine from a patient for diagnostic tests. Purpose The purpose of obtaining a urine sample is to test for any abnormalities that may be present, such as bacteria , ketones, or drugs.
|
|
A urine dipstick is a colorimetric chemical assay that can be used to determine the pH, specific gravity, protein, glucose, ketone, bilirubin, urobilinogen, blood, leukocyte, and nitrite levels of an individual ' s urine. It consists of a reagent stick-pad, which is immersed in a fresh urine specimen and then withdrawn.
