    B-cell leukemia/lymphoma panel

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    B-cell leukemia/lymphoma panel is a blood test that looks for certain proteins on the surface of white blood cells called B-lymphocytes. The proteins serve as markers that may be helpful in diagnosing or lymphoma.

    Bence-Jones protein - quantitative

    The urinary system is made up of the kidneys, ureters, urethra and bladder.

    A quantitative Bence-Jones protein test measures the specific level of abnormal proteins (Bence-Jones proteins) in your urine.

    Bleeding disorders

    Bleeding disorders are a group of conditions in which there is a problem with the body’s blood clotting process. These disorders can lead to heavy and prolonged bleeding after an injury. Bleeding can also begin on its own. See also: (types I, II, and III)

    Bleeding time

    The bleeding time test is used to evaluate how well a person's blood is clotting.  The test evaluates how long it takes the vessels cut to constrict and how long it takes for platelets in the blood to seal off the hole.  Blood vessel defects, platelet function defects, along with many other conditions can result in prolonged bleeding time.

    Bleeding time is a blood test that looks at how fast small blood vessels in the skin close to stop you from bleeding.

    Blood clots

    A thrombus is a blood clot that forms in a vessel and remains there. An embolism is a clot that travels from the site where it formed to another location in the body. Thrombi or emboli can lodge in a blood vessel and block the flow of blood in that location depriving tissues of normal blood flow and oxygen. This can result in damage, destruction (infarction), or even death of the tissues (necrosis) in that area.

    Blood clots are clumps that occur when blood hardens from a liquid to a solid. A blood clot that forms inside one of your veins or arteries is called a thrombus. A thrombus may also form in your heart. A thrombus that breaks loose and travels from one location in the body to another is called an . A ...

    Blood differential

    Basophils are a specific type of white blood cell. These cells are readily stained with basic dyes (this is where the name comes from). Note the dark grains inside the cellular fluid (cytoplasm) of this basophil. Basophils make up only a small portion of the number of white blood cells but are important parts of the body's immune response. They release histamine and other chemicals that act on the blood vessels when the immune response is triggered.

    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:

    Blood smear

    Sickle cell anemia is an inherited blood disease in which the red blood cells produce abnormal pigment (hemoglobin). The abnormal hemoglobin causes deformity of the red blood cells into crescent or sickle-shapes, as seen in this photomicrograph.

    A blood smear is a blood test that gives information about the number and shape of blood cells.

    Blood typing

    Antibodies from an Rh negative mother may enter the blood stream of her unborn Rh positive infant, damaging the red blood cells (RBCs). The infant responds by increasing RBC production and sending out immature RBCs that still have nuclei. This photograph shows normal RBCs, damaged RBCs, and immature RBCs that still contain nuclei.

    Blood typing is a method to tell what specific type of blood you have. What type you have depends on whether or not there are certain proteins, called antigens, on your red blood cells. Blood is often grouped according to the ABO blood typing system. This method breaks blood types down into four ...

    Bone marrow aspiration

    A small amount of bone marrow is removed during a bone marrow aspiration.  The procedure is uncomfortable, but can be tolerated by both children and adults.  The marrow can be studied to determine the cause of anemia, the presence of leukemia or other malignancy, or the presence of some "storage diseases" in which abnormal metabolic products are stored in certain bone marrow cells.

    Bone marrow is the soft tissue inside bones that helps form blood cells. It is found in the hollow part of most bones. Bone marrow aspiration is the removal of a small amount of this tissue in liquid form for examination. See also:

    Bone marrow biopsy

    A small amount of bone marrow is removed during a bone marrow aspiration.  The procedure is uncomfortable, but can be tolerated by both children and adults.  The marrow can be studied to determine the cause of anemia, the presence of leukemia or other malignancy, or the presence of some "storage diseases" in which abnormal metabolic products are stored in certain bone marrow cells.

    A bone marrow is the removal of soft tissue, called marrow, from inside bone. Bone marrow is found in the hollow part of most bones. It helps form blood cells.

    Bone marrow culture is an examination of the soft, fatty tissue found inside certain bones. This tissue, called bone marrow, produces blood cells. This test is done to find out if there is an infection inside the bone marrow.

    Bone marrow transplant

    A small amount of bone marrow is removed during a bone marrow aspiration.  The procedure is uncomfortable, but can be tolerated by both children and adults.  The marrow can be studied to determine the cause of anemia, the presence of leukemia or other malignancy, or the presence of some "storage diseases" in which abnormal metabolic products are stored in certain bone marrow cells.

    A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Bone marrow is the soft, fatty tissue inside your bones. Stem cells are immature cells in the bone marrow that give rise to all of your blood cells.

    Burkitt lymphoma

    The lymphatic system filters fluid from around cells.  It is an important part of the immune system.  When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes.  Common areas where lymph nodes can be easily felt, especially if they are enlarged, are: the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).

    Burkitt lymphoma is a very fast growing form of .
