Blood Tests



The Little Fighters Cancer Trust has been hard at work behind the scenes researching and documenting the most common type of test and procedures that your child may have to undergo in an effort to help you better understand and take some stress off of you.

We have tried our level best to lay it all out in simple terms and provide as much information as possible, including videos where possible.

This page will introduce you to vital information regarding Blood Tests that are normally done for Childhood Cancer.

Please go through the pages when you have some time – they will always be there for your edification. If at any stage you need some information about a new test or procedure, just type the name into the “search” box at the top right of the blog and you will get a list of any pages or articles containing that reference.

Blood Tests


Blood Studies

blood studiesBlood studies are tests that examine a patient’s blood. They are the most common tests done for cancer patients. They help doctors follow the course of a patient’s disease and select the right treatment dosage.

Blood can be drawn in a variety of ways, depending on your child’s situation. The most common way to draw blood is to insert a needle into a vein.

However, children undergoing chemotherapy may have a central venous line in place from which blood can be drawn.


Bone Marrow Aspiration

Bone-Marrow-AsipirateA bone marrow aspiration is a test to see if cells in the bone marrow are healthy. Bone marrow is the “factory” where blood cells are made. Bone marrow is found in the center of bones and is made up of both spongy bone and liquid marrow.

For this test, a needle is placed in a bone (usually the hipbone) and a small amount of liquid bone marrow is pulled into a syringe (usually 1-3 teaspoons). It is sent to the laboratory to be tested for cancer cells.


Bone Marrow Biopsy

Bone-Marrow-Biopsy-WebA bone marrow biopsy is used to study an actual piece of spongy bone marrow. It may be completed at the same time as a bone marrow aspirate.

For this test, a needle is placed in a bone (usually the hipbone); a small piece of spongy bone marrow is removed and sent to the laboratory to be tested.
