Mire való a vizsgálat?

Anémia (vérszegénység) vagy neuropátia (idegbántalom) okának tisztázására; vitamin ellátottság (tápláltsági állapot) felmérésére; B12 vitamin vagy folát hiány kezelésekor a terápia nyomon követésére.

Mikor kell a vizsgálatot elvégezni?

Kóros teljes vérkép vizsgálat esetén, amennyiben a perifériás vérkenetben nagy méretű vörösvértestek (makrociták) és abnormális (hiperszegmentált) neutrofil granulociták láthatók; anémia (gyengség, fáradékonyság, sápadtság) és/vagy neuropátia (bizsergő vagy viszkető érzés, a szemizmok akaratlan rángása, memóriazavar, megváltozott mentális státusz) tüneteinek jelentkezésekor; B12 vitamin vagy folát hiány kezelése során.

Milyen mintára van szükség?

A kar egy könyökhajlati vénájából nyert vérmintára.

Hogyan készüljek elő a vizsgálatra?

A mintavétel előtt 6-8 órás éhezés javasolt. Bizonyos gyógyszerek befolyásolhatják a tesztek eredményét; ezzel kapcsolatban kövesse kezelőorvosa utasítását.
