  • Thyroid Uptake Measurement
    • This test is used to determine the amount of radioactive iodine to be administered for therapy and to differentiate Grave’s Disease from thyroiditis and factitious hyperthyroidism
  • Total Glomerular Filtration Rate determination (GFR) using In-Vitro Method
  • Urea Breath Test
    • This test is a rapid diagnostic procedure used to identify infections caused by Helocobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer and peptic ulcer diseases.


What is Nuclear Medicine?

     Nuclear Medicine is a specialty that uses very small amounts of unseasles radiolabeled compounds to document organ function and structure in order to identify abnormalities early in the course of a disease. Nuclear Medicine also utilizes radioisotopes for targeted therapies of various benign and malignant diseases and the detection of antigen-antibody reactions.

What is Radioimmunoassay (RIA)?

     Radioimmunoassay is a very sensitive, specific laboratory test that uses radiolabeled substances in an immunologic (antibody-antigen)mreaction. RIA is able to detect nano or picomoles of molecules. Immunoassay plays a crucial role in the evaluation of the functional integrity of the patient’s organs.

What is Hyperthyroidism?

     Hyperthyroidism is a medical condition where the thyroid gland becomes overactive and produces excessive amounts of T3 or T4 or both. The most common cause of Hyperthyroidism is Grave’s Disease, an autoimmune disease characterized by the triad of Hyperthyroidism, goiter and buldging eyeballs.

How is Hyperthyroidism treated?

     Radioactive iodine therapy shrinks the enlarged and overactive thyroid gland through a radioactive solution or capsule that the patient swallows provided that the patient is not pregnant or lactating.

What is Radioactive Iodine Ablation?

Iodine Ablation is a treatment for Thyroid cancer and metastasis administered after thyroid surgery.

How are the treatments managed?

     AUFMC Nuclear Medicine Center has two specially designed and shielded rooms to provide adequate isolation to patients and radiation protection to others. In-patients are monitored daily by special equipment to determine the level of radioactivity considered safe before discharge.

Radioimmunoassay Tests:

    • TSH
    • FT3
    • FT4
    • Total T3
    • Total T4
    • Anti-TPO
    • Thyroglobulin
    • Anti-Thyroglobulin
    • Estradiol
    • Prolactin
    • Testosterone
    • ACTH
    • Cortisol
    • Aldosterone
    • Growth Hormone
    • Igf-1
    • C-Peptide
    • CA 19-9
    • CA 45-3
    • Intact PTH
    • Renin
    • Ferritin
    • Digoxin

     The AUFMC Nuclear Medicine Center uses the most advanced, top of the line Walla Wizard Gamma Counter for Radioimmunoassay Testing and Analysis.

     The AUFMC Nuclear Medicine Center is only the second hospital in the Philippines and the only one North of Manila to use the Walla Wizard 2470 Gamma Counter, one of the best performing gamma counters in this field.

     The center also boasts of qualified and highly regarded physicians and technologists to operate the machines and conduct radionuclide therapies.
