Common Patient Test and Procedures are listed below:
THYROID ULTRASOUND
Purpose:
To examine the thyroid internally. Useful
for examining goiter or nodules.
Description:
High
frequency sound waves are use to produce an image of the thyroid which
is projected onto a screen. This imaging technique is performed and interpreted in
our office by The Endocrine Center physicians.
Patient instructions:
None.
Complications:
None.
FNA (Fine Needle Aspiration) BIOPSY OF THYROID
Purpose:
To obtain samples of thyroid
tissue for examination under the microscope. Useful for determining
whether nodules are malignant (cancerous).
Description:
A
thin needle is inserted through the skin into the thyroid, and gentle suction
is applied with a syringe. Small amounts of tissue are spread onto
a slide and examined under the microscope. This biopsy technique is
performed by our physicians in our office. Ultrasound is often used
for guidance.
Patient instructions:
To
prevent excessive bleeding, discontinue blood thinners (Coumadin), aspirin
or certain pain relievers (ibuprofen) 2-3 days prior to the procedure.
Complications:
Localized pain,
bruising.
CORTROSYN STIMULATION TEST
Purpose:
To test for adrenal insufficiency
(low cortisol secretion).
Description:
Blood
samples are drawn before and after the intramuscular injection of a synthetic
hormone (cosyntropin), which stimulates adrenal function.
Patient instructions:
Fast
after midnight the morning of the test. Arrive at the testing center
by 8 AM.
Complications:
Bruising
at injection site.
DEXAMETHASONE SUPPRESSION TEST
Purpose:
To test for excessive cortisol
production (Cushing's syndrome).
Description:
A
synthetic hormone (dexamethasone) is taken by mouth. Eight hours
later a blood sample is drawn.
Pateint instructions:
Take
the dexamethasone tablet between 11PM and midnight. Arrive at the
testing center by 8 AM for blood draw.
Complications:
None.
24 HOUR URINE COLLECTION
Purpose:
Commonly
used to test for excessive production of cortisol and adrenalin or excessive
excretion of calcium.
Patient instructions:
