Radioactive iodine uptake test

Radioactive iodine uptake test

A radioactive iodine uptake test also called a thyroid uptake test, can help check thyroid function and find the cause of hyperthyroidism. The thyroid “takes up” iodine from the blood to make thyroid hormones, which is why this is called an uptake test. Your health care professional may ask you to avoid foods high in iodine, such as kelp, or medicines containing iodine for a week before the test.

Swallow a small amount of radioactive iodine: For this test, you will swallow a small amount of radioactive iodine in liquid or capsule form. During the test, you will sit in a chair while a technician places a device called a gamma probe in front of your neck, near your thyroid gland. The probe measures how much radioactive iodine your thyroid takes up from your blood. Measurements are often taken 4 to 6 hours after you swallow the radioactive iodine and again at 24 hours. The test takes only a few minutes.

Graves’ disease: If your thyroid collects a large amount of radioactive iodine, you may have Graves’ disease, or one or more nodules that make too much thyroid hormone. You may have this test at the same time as a thyroid scan.

A small amount of radiation: Even though the test uses a small amount of radiation and is thought to be safe, you should not have this test if you are pregnant or breastfeeding.

Shorter half-life: 123I has a shorter half-life than 131I (a half day vs. 8.1 days), so the use of 123I exposes the body to less radiation, at the expense of less time to evaluate delayed scan images. Furthermore, 123I emits gamma radiation, while 131I emits gamma and beta radiation.

Paul Mamu becomes part of Dharwad's history

People originally from Dharwad and most of whom migrated decades ago elsewhere across the state, country and world in search of green pastures were in for a sudden shock since late evening on Monday. They all shared similar sentiments, fond moments and profound grief in the passing away of Paul Cardoza of the renowned Hotel PAUL’S at Vidyagiri. He was 69 years old and not at all an age for his generation to bid adieu. Walks to Death: Paul Cardoza was a little bit hefty for his height and age; otherwise there were no visible symptoms to hint of any ailments he had been challenged with. Even on the fateful day, he attended to the chores in the hotel until the afternoon before proceeding to neighbour Hubballi for a cardiac test. It is said that he literally walked to the health check-up facility to undergo the examination. No, he was not destinated for it as he suffered a massive stroke and never to recover! A jovial personality: In the passing away of Paul Cardoza Dharwad has lost one o

Dr Godwin Shiri: An Accomplished Theologist, Author, Research Scholar and Social Scientist..

Dr Godwin Shiri as the name itself suggests is truly a Godly person who won the hearts of people all along and wherever he went across the globe. He is a well-read, widely travelled religious personality having contributed any number of books and translations of eminent philosophers. He is turning 79 today and looking back there seems to be a huge list of accomplishments worth cherishing on the way. Priest on his own inclination: Dr Godwin Shiri himself voluntarily opted for the priestly vocation of becoming a Pastor at a young age, much against the wishes of his family. The sight of the Cross of Lord Jesus Christ and the scenario of thousands of workers marching holding red flags in his native town Mangaluru had a lasting effect on him as a young boy. Recalling the good old days Godwin Shiri admits-"Perhaps they sowed in me the seeds of compassion and social justice".
