The
laboratory performs many different types of testing. The tests may
be done on blood, urine, tissue or other body fluids. The results
of these tests will be sent to your doctor to help him make decisions
about your treatment.
Blood
specimens may be used to diagnose conditions such as Anemia, Hypertension,
Infection or other diseases. It may also be used to screen for conditions
that are preventable with early detection such as high cholesterol,
diabetes or certain types of cancer.
Blood
Collection
A
Phlebotomist is a person that is trained to collect blood specimens
from patients. Blood specimens may be collected by a procedure called
a veinipuncture or by a finger stick.
Veinipuncture
is a procedure where a small needle is inserted into the vein. A
tube is attached to the needle to draw a sample of blood directly
into the tube. The tests may require one or more tubes of blood
to be collected. A finger stick is used on infants or in cases where
only a small amount of blood is needed for testing.
You may be asked not to eat or drink for 12 hours. Your physician
will give you any special preparation instructions if necessary
for the test.
Because a needle is inserted into the skin some pain may be felt
during the procedure. This may vary from patient to patient due
to factors affecting the patients physical condition or during a
difficult draw.
Bleeding at the site usually stops within a few minutes after the
procedure. Patients taking medications may bleed a little longer.
Pressure will be applied to the site until bleeding has completely
stopped.
Some
bruising or swelling may occur at the site. This is caused by some
blood leaking into the skin during the procedure. A small amount
of bruising may be normal but you should contact your healthcare
provider immediately if the area becomes red and painful.
Occasionally
a patient may feel dizzy or faint at the sight of blood. If you
feel unusual during the procedure or immediately following, you
should notify the phlebotomist and move to a seated position.
approximately 15-30 minutes
As always, please let your doctor or the phlebotomist know if
you have any concerns or questions regarding your lab work.
