The normal values of thyroid uptake of radiotracer are 3 to 16% at 6 hours and 8 to 25% at 24 hours. These values may change according to laboratory standard techniques or patient dietary habits. The thyroid gland can uptake more or less than normal.

What does increased thyroid uptake mean?
A high uptake of tracer spread evenly in the thyroid gland may mean that hyperthyroidism is caused by conditions such as Graves’ disease.
What is the normal 24 hour radioactive iodine uptake?
These are normal results at 6 and 24 hours after swallowing the radioactive iodine: At 6 hours: 3% to 16% At 24 hours: 8% to 25%
What does a thyroid uptake scan show?
A thyroid uptake and scan is a diagnostic imaging scan that allows the radiologist to determine the function of the thyroid. This scan can determine if the patient has thyroid cancer: persistent or recurrent disease, hyperthyroidism and thyroid nodule or goiter assessment.
What is an I 131 uptake test?
Radioactive iodine uptake test is a type of nuclear test performed to evaluate thyroid function. The patient ingests radioactive iodine (I-123 or I-131) capsules or liquid.
What are early warning signs of thyroid problems?
Early signs of thyroid problems include:
- Gastrointestinal problems.
- Mood changes.
- Weight changes.
- Skin problems.
- Sensitivity to temperature changes.
- Vision changes (occurs more often with hyperthyroidism)
- Hair thinning or hair loss (hyperthyroidism)
- Memory problems (both hyperthyroidism and hypothyroidism)
What happens after thyroid uptake scan?
Thyroid scans and uptake tests do not generally cause any after effects. Through the natural process of radioactive decay, the small amount of radioactive chemical in your body will lose its radioactivity over time.
What is the difference between i-123 and i 131?
Iodine, in the form of iodide, is made into two radioactive isotopes that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells. RAI is safe to use in individuals who have had allergic reactions to seafood or X-ray contrast agents.
What is a NM thyroid scan pertechnetate?
Tc-99m pertechnetate thyroid scan is a functional nuclear medicine study used to assess the thyroid gland. The uptake of the pertechnetate anion – similar in chemical-physical characteristics to the iodide ion – in the thyroid parenchyma is mediated by the NIS (Sodium-Iodide Symporter).
How much is a thyroid uptake scan?
How Much Does a Thyroid Uptake and Scan Cost? On MDsave, the cost of a Thyroid Uptake and Scan ranges from $341 to $812. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.
What do cancerous thyroid nodules look like on an ultrasound?
A malignant thyroid nodule tends to have ill-defined margins on ultrasound (Fig. 1). A peripheral halo of decreased echogenicity is seen around hypoechoic and isoechoic nodules and is caused by either the capsule of the nodule or compressed thyroid tissue and vessels .
What is the main cause of Graves disease?
Graves’ disease is caused by a malfunction in the body’s disease-fighting immune system. It’s unknown why this happens. The immune system normally produces antibodies designed to target a specific virus, bacterium or other foreign substance.
What are the symptoms of thyroid problems in females?
Hypothyroidism signs and symptoms may include:
- Increased sensitivity to cold.
- Dry skin.
- Weight gain.
- Puffy face.
- Muscle weakness.
How can I tell if my thyroid is enlarged?
Examining your neck in the area of the Adam’s apple while you swallow can sometimes detect if your thyroid is enlarged. Swallow while tipping the head back, and examine your neck and the area above the collarbones. If you see any lumps or bulges, see a doctor.
What is a thyroid storm?
Thyroid storm is a very rare, but life-threatening condition of the thyroid gland that develops in cases of untreated thyrotoxicosis (hyperthyroidism, or overactive thyroid). The thyroid gland is located in the neck, just above where your collarbones meet in the middle.
What is I 123 uptake and scan?
What is I-123 Uptake and Scan? An I-123 Uptake and Scan is a trace amount of radioactive iodine that is used to evaluate the thyroid gland for in physiological abnormalities. Patient Prep: Prior to the procedure the patient has to be off of all thyroid medication for. a minimum of 2 weeks.
