Opis
Szczegóły produktu

Cel badania.

Określanie poziomu witaminy D jest potrzebne do oceny konieczności wdrożenia suplementacji daną witaminą, pozwala na wykrycie niedoboru witaminy D w organizmie bądź jej przedawkowaniu.

Opis badania.

Witamina D jest produkowana w skórze pod wpływem promieni UV. Jej nie aktywne biologicznie postaci ulegają hydroksylacji w komórkach wątroby do postaci 25-hydroksywitaminy D (25-OH), głównej formy krążącej we krwi. A ta w nerkach zamienia się w najbardziej aktywną 1,25-OH witaminę D. Witamina D należy do witamin rozpuszczalnych w tłuszczach, dlatego gromadzi się w tkankach i istnieje możliwość jej przedawkowania. Poziom witaminy D wpływa na gospodarkę wapniowo-fosforanową poprzez regulację wchłaniania wapnia. Zalecane jest oznaczanie poziomu witaminy D osobom starszym, kobietom po menopauzie, u których zauważalna jest zwiększona częstość złamań kości. Warto też sprawdzać poziom witaminy D u osób z osłabioną odpornością, częstymi infekcjami, z upośledzonym wchłanianiem z przewodu pokarmowego, będącym na diecie eliminacyjnej. Ważna jest suplementacja witaminą D u dzieci, zapewnia prawidłowy rozwój kości i zapobiega rozwojowi krzywicy.

Przygotowanie do badań.

Oznaczenie poziomu witaminy D należy wykonywać przed rozpoczęciem jej suplementacji. Zalecane jest pobranie krwi do badania poziomu witaminy D rano, na czczo. Jednak pobranie w ciągu dnia nie wpływa na wynik badania.
