Iodine 20 - 30 Mci, in Mysuru

Fasting and dietary instructions:

An overnight fast of 10 to 12 hours is recommended. Eat your last meal the previous evening. On the day of the test, drink plain water freely until your appointment. Avoid alcohol, heavy fatty meals, and vigorous exercise the evening before, as these can temporarily affect several common blood markers.

Medication guidance:

If you are on levothyroxine (thyroid hormone replacement), do not take your morning dose before the blood draw , have the sample collected first, then take your medication. This gives the most accurate reading of your baseline thyroid hormone level before the daily dose is absorbed into the system.

What to bring:

Bring your doctor's test requisition or prescription, a valid government-issued photo ID, and your health insurance card if you plan to use cashless OPD benefits. Wear clothing that allows easy access to the inside of your elbow , a short-sleeved top or a sleeve that can be rolled up comfortably.

Timing:

Morning appointments are recommended for most blood tests. Biological markers tend to be most stable before meals and physical activity, giving the most consistent, comparable results. Booking an early slot also means you can eat and resume normal activity sooner after the test.

When does a doctor order Iodine 20 - 30 Mci?

Endocrinologists order Iodine 20 - 30 Mci routinely for all patients receiving thyroid medication, for pregnant women (thyroid dysfunction affects foetal development), for individuals with a family history of thyroid disease who have never been screened, and for post-thyroidectomy patients who need lifelong hormone monitoring.

Who should get Iodine 20 - 30 Mci done?

Iodine 20 - 30 Mci is used as a thyroid uptake scan to assess how actively the thyroid takes up iodine. It is often ordered with thyroid blood tests when symptoms like weight change, tremor, palpitations, heat intolerance, or a noticeable neck lump occur. People with autoimmune conditions , including type 1 diabetes, rheumatoid arthritis, lupus, or Sjogren's syndrome , face a substantially higher risk of autoimmune thyroid disease (Hashimoto's or Graves') and should be screened at least annually. Anyone on amiodarone or lithium (medications known to affect thyroid function) also requires regular monitoring.
