An observational study in Hyperthyroidism, sponsored by Superior University. Active, not recruiting at 1 site in Pakistan. Open to participants aged 20 Years to 40 Years. Per ClinicalTrials.gov, last updated 2025-07-02.
Sponsored by Superior University · Observational
"This study is designed to evaluate the thyroid health of healthcare workers exposed to low-dose ionizing radiation at INMOL Cancer Hospital, Lahore. Specifically, it investigates whether prolonged occupational exposure in radiology and nuclear medicine departments is associated with altered thyroid hormone levels or an increased risk of hypothyroidism. The thyroid gland is highly sensitive to radiation, and existing literature suggests a possible link between occupational exposure and thyroid dysfunction.
A cross-sectional research design will be used over a four-month period. A sample of 44 participants will be selected using purposive sampling from the hospital's radiology and nuclear medicine staff.
112 studies on the registry are indexed under Hyperthyroidism; 27 are open to participants now.
This study's enrollment of 44 is below the median of 98 across 48 observational studies indexed under Hyperthyroidism.

Behavioral: Thyroid Function Monitoring
This study will include healthcare professionals from the radiology and nuclear medicine departments at INMOL Cancer Hospital with at least one year of radiation exposure. A total of 44 participants will be selected through purposive sampling. Data will be collected using a structured questionnaire and blood tests for thyroid hormones (TSH, T3, T4) to assess thyroid function. Blood analysis will be conducted using CLIA or ELISA methods. The aim is to detect any association between low-dose radiation exposure and thyroid dysfunction.
thyroid function assessment
Thyroid function is assessed through blood tests, primarily measuring TSH (Thyroid Stimulating Hormone), T4 (Thyroxine), and sometimes T3 (Triiodothyronine) levels. Abnormal levels of these hormones can indicate an underactive (hypothyroidism) or overactive (hyperthyroidism) thyroid. Normal Ranges (approximate): TSH: 0.4 - 4.0 mIU/L Free T4: 0.7 - 1.9 ng/dL Total T4: 5.0 - 12.0 μg/dL Total T3: 80 - 220 ng/dL
