Examination of Skin

Diagnosis is suspected based on the appearance of the skin lesions, and strengthened by a prior history of chickenpox or shingles. It can be confused with herpes simplex. Tests are rarely necessary, but may include: Viral culture of skin lesion; T...

Diagnosis is usually not possible until the skin lesions develop. Once they develop, however, the pattern and location of the blisters and the type of cell damage displayed are very characteristic of the disease, allowing an accurate diagnosis pri...

Diagnosis is based on history and symptoms. The person must have initially had chicken pox in order to have shingles. Definite diagnosis is difficult before eruption of the characteristic vesicles or bumps on the skin. Often persons with early shi...

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 ) The mean corpuscular volume (MCV) -- the size of the red blood cells CBC also includes information about the red blood cells that is calculated from the other measurements: MCH (mean corpuscular hemoglobin) MCHC (mean corpuscular hemoglobin concentration) The platelet count is also usually included in the CBC.

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 (plasma). It involves determining the numbers, concentrations, and conditions of the different types of blood cells.

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 count; measurement of hemoglobin and mean red cell volume; classification of white blood cells (WBC differential); and calculation of hematocrit and red blood cell indices .

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 red cell count), has an infection (increased white blood cells), or has abnormal blood coagulation (platelet levels).

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 physical examination is an evaluation of the body and its functions using inspection, palpation (feeling with the hands), percussion (tapping with the fingers), and auscultation (listening). A complete health assessment also includes gathering information about a person ' s medical history and lifestyle, doing laboratory tests, and screening for disease.

 |
The health history is a current collection of organized information unique to the individual patient. Relevant aspects of the history include biographical, demographic, physical, mental, emotional, sociocultural, sexual, and spiritual data.

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.
