Fanconi anemia is an inherited form of aplastic anemia characterized by an abnormally low number of cellular components in the blood due to failing bone marrow.

The most common test for FA is called a chromosome breakage test. White blood cells are isolated from a patient's blood sample and destructive chemicals are added to these cells. The chromosomes are then viewed under a microscope. If the person is...

Amniocentesis is a diagnostic procedure performed by inserting a hollow needle through the abdominal wall into the uterus and withdrawing a small amount of fluid from the sac surrounding the fetus.

Amniocentesis is a procedure used to diagnose fetal defects in the early second trimester of pregnancy . A sample of the amniotic fluid, which surrounds a fetus in the womb, is collected through a pregnant woman ' s abdomen using a needle and syringe.

First, the fetus is located with ultrasound. A thin needle is then inserted into your belly. The doctor keeps the needle from touching the fetus by watching the screen.

Amniocentesis is an optional procedure offered to women during pregnancy in order to obtain more information about a developing fetus. A doctor uses a thin, hollow needle to remove a small sample of amniotic fluid from around the developing baby.

Amniocentesis is a procedure used to diagnose fetal defects in the early second trimester of pregnancy. A sample of the amniotic fluid, which surrounds a fetus in the womb, is collected through a pregnant woman ' s abdomen using a needle and syringe.

Amniocentesis is an optional but reliable procedure offered to pregnant women in order to obtain more information about a developing fetus in the second trimester of pregnancy . It is primarily offered to pregnant women who are at increased risk, based on their age, family history, or other factor, of having a child with a genetic condition.

Amniocentesis is a procedure used to diagnose fetal defects in the early second trimester of pregnancy. A sample of the amniotic fluid, which surrounds a fetus in the womb, is collected through a pregnant woman ' s abdomen using a needle and syringe.

A medical test that involves withdrawing a sample of fluid from the amniotic sac surrounding the fetus in the abdomen of the pregnant woman. Amniocentesis is a procedure used to detect the presence of genetic disorders such as Down syndrome and spina bifida in a fetus.

Bone marrow aspiration, also called bone marrow sampling, is the removal by suction of fluid from the soft, spongy material that lines the inside of most bones. Bone marrow biopsy , or needle biopsy, is the removal of a small piece of bone marrow.

Boning Up on MarrowYou may think of your bones as similar to the girders that support a skyscraper. Like I-beams, they're rigid and strong.But though bones may appear dense and solid, inside there's plenty going on.

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).

Chorionic villus sampling (CVS) is a procedure for taking a small piece of placental tissue (chorionic villi) from the uterus in the early stages of pregnancy to check for the presence of genetic defects in the fetus.

Chorionic villus sampling (CVS) is a prenatal procedure for the removal by needle of chorionic villi and culture and examination of the fetal cells obtained. The cells are used in tests for genetic and chromosomal abnormalities of a fetus as early as 10 to 12 weeks of gestation.

CVS is a test that helps you learn if a fetus has health problems. The test is most often done between weeks 9 and 11 of pregnancy.

Chorionic villus sampling (CVS), also known as chorionic villus biopsy, is a prenatal test that can detect genetic and chromosomal abnormalities of an unborn baby. Purpose Chorionic villus sampling is performed on pregnant women who are at risk for carrying a fetus with a genetic or chromosomal defect.

A hand x-ray is an examination involving images of one or both hands. X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray.

A tuning fork is a metal instrument with a handle and two prongs or tines. Tuning forks, made of steel, aluminum, or magnesium-alloy will vibrate at a set frequency to produce a musical tone when struck.

During the process of choosing a hearing aid, your hearing will be carefully tested by an audiologist. The test results, called an audiogram, will show whether your ears are healthy, what type of hearing loss you have, and exactly what you can and cannot hear.

What Is an Audiogram?The results of your hearing test are shown on a graph called anaudiogram.This graph shows which types of sounds you can and can’t hear.

Is an auditory brainstem response test a usual thing to have done for hearing loss?

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)

An MRI of the head is a non-invasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Unlike conventional radiography and computed tomography (CT), which make use of potentially harmful x-rays passing through a patient to generate images, MRI imaging is based on the magnetic properties of atoms. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. The "nuclear" in the original name (nuclear magnetic resonance imaging) -- now seldom used -- refers to the proton in the nucleus of the hydrogen atom and does not imply radioactivity. When focused short radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, they will return a signal of their own. The subtle differences in that signal from dissimilar tissues enables the MRI to differentiate between various organs, and potentially, provide contrast between benign and malignant (cancerous) tissue. Any imaging plane, or slice, can be projected, and then stored in a computer or printed on film. MRI is easily performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.
