Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- Thyroid ultrasonography (ultrasound examination of the thyroid gland) – as a basic examination to determine the size and volume of the thyroid gland, as well as any structural changes such as nodules; if necessary, with fine-needle biopsy.
- Ankle-brachial index (ABI; examination method that can describe the risk of cardiovascular disease) – if peripheral arterial occlusive disease (pAVD) is suspected.
- Electrical impedance analysis (measurement of body compartments/body composition) – for determination of body fat, extracellular body mass (blood and tissue fluid), body cell mass (muscle and organ mass) and total body water incl. body mass index (BMI, body mass index) and waist-to-hip ratio (THV) in case of underweight.
