Natriumjodid (131i) Diagnostikkapseln Ge Healthcare (Sodium Iodide (131i))

Sodium Iodide labeled with I‑131 is selectively absorbed by thyroid follicular cells via the sodium‑iodide symporter. Once inside the cells, the isotope emits gamma photons that are captured by a gamma camera, producing detailed images of iodine distribution within the gland. This selective uptake provides a clear picture of thyroid function and anatomy.

The administered activity of Natriumjodid (131i) Diagnostikkapseln is determined by the prescribing physician based on the specific diagnostic indication, patient age, weight, and the imaging protocol of the nuclear medicine department. Dosage is individualized and should follow local regulatory guidelines and the institution’s radiation safety standards.

Use of I‑131 sodium iodide during pregnancy is generally avoided because the radiation can cross the placenta and affect the fetus. In breastfeeding women, iodine can be secreted into breast milk, potentially exposing the infant. Therefore, the product should only be used if the benefit outweighs the risk and alternative imaging methods are not suitable.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity of Natriumjodid (131i) Diagnostikkapseln. GNH India works with hospitals, pharmacies, and procurement teams worldwide, and will request verification of trade or institutional credentials. After validation, the sales team provides pricing, availability, shipping details and assists with any necessary import documentation.

Natriumjodid (131i) provides both diagnostic imaging and a low therapeutic radiation dose, whereas non‑radioactive agents such as ultrasound offer structural information only. Compared with technetium‑99m pertechnetate, I‑131 has a longer half‑life and higher thyroid uptake, giving clearer functional images but requiring stricter radiation safety measures.

Store the capsules at ambient temperature, preferably below 25 °C. Keep them in the original container, protect from moisture and direct light, and ensure the packaging remains sealed until use. Do not refrigerate or freeze the product, as temperature extremes can affect capsule integrity.

The product is administered orally as a capsule. The patient swallows the capsule with water under the supervision of qualified nuclear medicine staff. After ingestion, a waiting period allows the iodine to concentrate in the thyroid before imaging is performed, typically ranging from a few hours to a day depending on the protocol.

Serious risks include allergic reactions such as anaphylaxis, radiation‑induced thyroiditis, and, rarely, bone marrow suppression due to systemic radiation exposure. Patients should be monitored for signs of hypersensitivity, persistent neck pain, or unexplained hematologic abnormalities, and any severe symptoms should prompt immediate medical evaluation.

The product should be avoided in pregnant women, nursing mothers, and patients with known hypersensitivity to iodine or radioactive substances. Individuals with severe uncontrolled thyroid disorders, recent exposure to high‑dose radioactive iodine therapy, or those unable to comply with radiation safety precautions should also be excluded.
