Transferriinireseptori, liukoinen (S -TfR)

Liukoisen transferriinireseptorin määrä kohoaa raudanpuutteessa.

S-TfR-testin avulla selvitetään, onko henkilöllä raudanpuutetta. Raudanpuute aiheuttaa esimerkiksi väsymystä ja heikkouden tunnetta.

Transferriinireseptori, liukoinen (S -TfR)

S-TfR-testi on yksi raudanpuutteen diagnostiikassa käytettävistä testeistä.
Arvo kuvaa punasolutuotannon vilkkautta ja kohoaa raudanpuutteessa.
Testin avulla tutkitaan, onko potilaalla raudanpuuteanemia vai johtuuko anemia muusta tekijästä.

Sisällysluettelo

Transferriinireseptori, liukoinen (S -TfR)

Transferriinireseptori on transferriinin eli raudan kuljettajavalkuaisen vastaanottajamolekyyli. Sen määrä veressä kuvaa punasolutuotannon vilkkautta. Liukoisen transferriinireseptorin määrä kohoaa raudanpuutteessa.

Seerumin transferriinireseptori -määritys (S -TfR) on mikrosyyttisen anemian selvittelyssä luotettavampi kuin tavalliset raudanpuutteen mittarit (seerumin rauta, transferriini ja ferritiini).

Mitä liukoisen transferriinireseptorin S-TfR-testillä tutkitaan?

Liukoisen transferriinireseptorin pitoisuuden mittaaminen auttaa selvittämään, onko henkilön anemian taustalla raudanpuute.

Raudanpuutetta tutkitaan myös esimerkiksi ferritiinitestillä.

Transferriinireseptorien määrä veressä lisääntyy raudanpuutteen aikana, jolloin myös S-TfR-arvo kohoaa. Korkea pitoisuus siis viittaa vahvasti raudanpuutteeseen. Harvinainen raudankertymäsairaus saattaa puolestaan laskea arvoa.

Missä voin mitata S-TfR-arvoni?

Voit ostaa S-TfR-testin Puhdin verkkokaupasta. Kaikki Puhdin testit ovat tilattavissa ilman lääkärin lähetettä.

Lääkärin etäkonsultaation voi tilata erikseen helposti suoraan tulosraportin lopusta, mikäli haluat keskustella tuloksistasi ja terveydestäsi, tulokset poikkeavat viitearvoista, sinulla on oireita tai herää epäilys sairaudesta.

Tutustu myös laajaan anemian ja raudanpuutteen tutkimuspakettiin.

S -TfR viitearvot

Miehet: 2.2 – 5.0 mg/l
Naiset: 1.9 – 4.4 mg/l

Viitearvot voivat vaihdella laboratorioittain ja tutkimusten analysointimenetelmästä riippuen. Puhdin näytteet otetaan ja analysoidaan Mehiläisen laboratorioissa.
