How Do You Know if You Are a Bone Marrow Match

What It Is

Bone marrow aspirations and biopsies are performed to examine os marrow, the spongy liquid part of the bone where blood cells are fabricated.

In a bone marrow aspiration, a pocket-size corporeality of liquid marrow is taken from inside the bone and then the cells can be examined under a microscope.

In a bone marrow biopsy, a small slice of intact bone marrow is removed so the structure of the bone marrow inside its bony framework can be examined.

Occasionally, only an aspiration is needed; other times, both tests are done.

The aspiration and biopsy are done by a trained medical practitioner (nurse or doctor) using a modest needle inserted into a os. Usually the dorsum of the hipbone (iliac crest) is used.

Why It's Washed

Doctors perform bone marrow aspirations and biopsies when they're concerned about a problem in the bone marrow. They can help to diagnose:

• the cause of anemia (also few red blood cells, which conduct oxygen through the body)
• the cause of thrombocytopenia (besides few platelets, which aid the blood to jell)
• the cause of an abnormal number of white claret cells, which fight infections
• cancers of the claret, such as leukemia
• whether cancers that started elsewhere take spread to the os marrow (the cess of how much a cancer has spread is called staging, and is important in determining treatment and prognosis)
• viral, bacterial, or fungal infections in the bone marrow that might be causing lasting fever or other symptoms
• certain genetic diseases (such as lipid storage diseases)

They as well may be done to collect a bone marrow sample for procedures (such as a stem jail cell transplant) or other testing (such as chromosomal analysis).

A small amount of anesthetic medicine will be injected through the numb spot on the pare to forestall pain equally the os marrow needle is inserted through the pare and soft tissues.

For the os marrow aspiration, the doctor or nurse will carefully insert a needle into the biopsy site and will then adhere a syringe to draw out a sample of fluid from within the os.

For the biopsy, a different kind of needle will be inserted into the same surface area to remove a small-scale sample of bone. A bandage volition then exist applied to the biopsy site.
