Blood tests

Blood tests

Blood tests are done to look for blood diseases and

signs of other diseases. Blood is often removed from

a vein in the inside of the elbow with a needle. The

needle may bruise your skin and you may feel dizzy

from the blood draw. Your blood will be sent to a lab

for testing. Blood tests for Hodgkin lymphoma are:

Complete blood count with differential

A CBC (

c

b

lood

c

ount) measures the number

of blood cells in a blood sample. It includes numbers

of white blood cells, red blood cells, and platelets.

Your blood counts may be low or high because of

cancer or another health problem.

There are five types of white blood cells. A differential

counts the number of each type. It also checks if

the counts are in balance with each other. Your

doctor can learn from this test what the cause of an

abnormal white blood count is.

Erythrocyte sedimentation rate

ESR (

e

rythrocyte

s

edimentation

r

ate) is the amount

of clear fluid at the top of a tube after one hour. It is

used to decide if you have inflammation. Inflammation

is your body’s attempt to heal itself. A large amount

of clear fluid (a high ESR) may be caused by

inflammation or something else, so other tests may

be given.

Comprehensive metabolic panel

Chemicals in your blood come from your bone, liver,

and other organs. A comprehensive metabolic panel

often includes tests for 14 chemicals. The tests show

if the level of chemicals is too low or high. Abnormal

levels can be caused by cancer or other health

problems.

Lactate dehydrogenase test

Lactate dehydrogenase is a protein that is in most

cells. It gets into your blood when a cell is damaged.

Thus, a high level of lactate dehydrogenase is a sign

of cell damage. High levels can be caused by cancer

or other health problems.

Liver function test

Your liver is an organ in the upper right side of your

abdomen. It does many important jobs, such as

remove toxins from your blood. A liver function test

assesses for chemicals that are made or processed

by the liver. Levels that are too high or low may signal

that the cancer has spread to the liver.

HIV testing

If you have HIV, treating it is an important part of

treating Hodgkin lymphoma. HIV treatment will

improve how well cancer treatment works. Thus, tell

your treatment team if you have HIV and about your

treatment. For others, ask your treatment team if you

should get tested.

Hepatitis B testing

Like HIV, hepatitis B can affect how well some cancer

treatments work. Thus, tell your treatment team if you

have hepatitis B. For others, ask your treatment team

if you should get tested.
