Iodine (Iodine, I) is a trace element that the human body requires primarily for the synthesis of thyroid hormones. Furthermore, iodine can also be used therapeutically in the context of thyroid dysfunction (euthyroid goiter).
The procedure
Material needed
- Spontaneous urine
Preparation of the patient
- Not necessary
Disruptive factors
- Not known
Normal value
| Normal values of iodine in μg/g creatinine | 150-250 |
Assessment
| Measured iodine value in μg/g creatinine. | Assessment |
| 50-100 | Mild iodine deficiency |
| 10-50 | Moderate iodine deficiency |
| < 10 | Severe iodine deficiency |
| > 1.000 | Iodine contamination |
Indications
- Suspected iodine deficiency
- Suspicion of iodine contamination and hyperthyroidism (hyperthyroidism) triggered by it.
Interpretation
Interpretation of increased values
- Iodine contamination
Interpretation of lowered values
- Iodine deficiency
Other indications
- The iodine determination can not give binding statements about the individual iodine stock. Therefore, iodine determination is usually performed only in the context of epidemiological studies.
- The results of the nationwide DEGS study (Health of Adults in Germany) showed the following urine iodine concentration (UIC):
- Median UIC men 69 µg /l and women 54 µg /l.
- The measurement results are thus well below the WHO limit for adequate iodine supply (100 µg /l)!
- Estimated median 24-h UIE was 113 µg /day. 32% of participants did not reach the estimated median requirement (EAR) of iodine.
- Median UIC men 69 µg /l and women 54 µg /l.
- The normal requirement for iodine in women as well as men is 200 µg/d.
Attention. Note on the supply status (National Consumption Study II 2008) Without taking into account the use of iodized table salt In the age group of 19-80 LJ. reach only 1-6% of women and only 3-5% men the intake recommendation. The worst supplied men and women lack about 130-160 µg iodine. (DGE recommendations: 19th-50th year 200 µg/day, 51> year 180 µg/day).
Taking into account the use of iodized salt, only 26-61% of women and only 70-80% of men in the 19-80 age group reach the recommended intake. The worst supplied men lack about 60-75 µg iodine and the women about 75-110 µg iodine. The deficits are greatest in the age group from 19 to 50 years. (DGE recommendations: 19th-50th yr. 200 µg/day, 51> yr. 180 µg/day).
