Oestrogeenmetabolieten

Oestrogenen worden door hydroxilatie, sulfatie, methylatie of glucoronidase in de lever verwerkt tot zogenaamde metabolieten (stofwisselingsproducten). Dit zijn wateroplosbare vormen van oestrogeen, zodat het hormoon kan worden uitgescheiden via urine en ontlasting. Oestrogeen zelf is een vetachtige stof en kan daarom niet direct worden uitgescheiden. 

Er zijn vijf metabolieten van oestrogeen. Deze vijf metabolieten hebben echter nog steeds een oestrogene werking. De ene metaboliet werkt krachtiger en specifieker dan de ander.

Milde, beschermende werking:
2OH-oestron

Sterke, tumor-stimulerende werking:
4OH-oestron
16aOH-oestron

Deze hormonen sturen celdeling in oestrogeengevoelige cellen aan.

Niet actieve metabolieten:
2 methoxy-oestron
4 methoxy-oestron

Deze metabolieten kunnen wel een oestrogeenreceptor bezetten en verhinderen daarmee dat de actieve metabolieten zorgen voor celdeling.

Frequently asked questions

Answers to what people usually want to know.

How does the home test work from A to Z?

After ordering we ship the collection kit to your home. You collect urine following the instructions, return it in the envelope, and receive your result digitally by email.

How do I collect my urine sample correctly?

Follow the included instructions, usually the midstream method in a sterile container. Pay attention to the right timing (first morning urine or random, depending on the test).

Do I need to avoid anything before collection?

For some tests yes (e.g. certain foods or supplements). Whether this applies is stated in the instructions. Read them before you start.

How do I return the sample?
