Doctor comment

Your magnesium and vitamin D are markedly reduced. This can contribute to fatigue, muscle cramps and lower immunity. Supplements are generally available over the counter in the Netherlands. At your levels, however, we advise read more ›

Vanuit de sportschool geattendeerd op Bloodworks en heel tevreden. Bloedonderzoek online besteld en kon direct terecht bij een lab in de buurt. Kreeg het labformulier per e-mail en na het prikken de resultaten met uitleg ontvangen. Kom hier zeker vaker terug!

Ik heb eerder onderzoeken laten uitvoeren door andere organisaties, maar Bloodworks steekt daar met afstand bovenuit. De snelle service, het persoonlijke contact en de transparantie hebben ervoor gezorgd dat ik al mijn vervolgonderzoeken hier laat uitvoeren.

Na geregeld duizelig te voelen ben ik langs geweest bij Bloodworks voor een bloedtest, snelle service en super snel uitslag gekregen! Advies gekregen van de specialisten om een aantal waardes aan te vullen, en daadwerkelijk geen last meer van mijn klachten. Super dankbaar, vakkundig en bekwaam.

FAQ

Frequently asked questions

Do I need to fast?

Fasting is not strictly necessary, but serum iron fluctuates during the day. We recommend testing in the morning between 8 and 10 o'clock for the most comparable result, especially for a repeat measurement.

I take iron tablets, can I still test?

Iron supplementation temporarily raises serum iron sharply. For a reliable picture of your iron stores, we advise stopping iron tablets at least 24 to 48 hours before the test. Always let us know about supplement use so our doctor can take it into account.

Why measure both ferritin and iron?

Ferritin reflects your iron stores, while serum iron, transferrin and saturation show how iron is transported. Together they give a more complete picture than a single value and help distinguish a true deficiency from an inflammatory response.

Is this the same as a test for anaemia?

This panel focuses on your iron status, the most common cause of anaemia. If you also want your red blood count (haemoglobin) measured, you can add it via Bloodworks Select or choose a broader package such as Bloodworks Plus.

How quickly do I receive my results?

Typically within a few working days of blood draw. You will receive an email as soon as your personal report with doctor interpretation is ready.
