Sufficient vitamin D supply is essential for general health. The total 25-hydoxy-vitamin-D (t-25OHD) level refers to the vitamin D supply and can be measured with various methods. Since these methods are not independent of the serum matrix, differences can be obtained among vitamin D levels measured with different methods. Our aim was to study the vitamin D in healthy blood donors, taking also into consideration the use of oral contraceptives (OC).Method...

Macroprolactin levels in healthy blood donors

The incidence of macroprolactinemia decreased notably because of wide use of prolactin (PRL) assays measuring macroprolactin at a lower rate. However, in case of high PRL levels, measurement of monomeric PRL (mPRL) levels after polyethylene glycol (PEG) treatment is still required. Our aim was to determine – by the use of a second generation PRL assay – how total PRL (tPRL) levels in native sera of healthy blood donors change after PEG treatment. In women, the use of...
