Zinc is an essential mineral crucial for the functioning of the immune system, DNA synthesis, wound healing, and cell growth. It also plays an important role in maintaining healthy skin, eyes, and the heart.
Testing for zinc is useful for identifying deficiencies or excesses in the body, which can lead to various health problems. It is particularly important for people at risk of deficiency, such as vegetarians, pregnant women, and the elderly, or for those experiencing symptoms that may indicate a zinc deficiency or excess.
A zinc test indicates the amount of zinc in the blood. This is an indication of the body's zinc reserves and whether they fall within a healthy range.
A high zinc level may indicate an excess, which could potentially lead to negative effects such as nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headache. Long-term exposure to high levels can also interfere with the absorption of other important minerals.
A low zinc level may point to a deficiency, which can affect essential bodily functions. Symptoms of a zinc deficiency might include reduced immune function, hair loss, diarrhea, delayed wound healing, and loss of taste or smell.
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Zink in serum is een gevestigde bepaling in de Nederlandse zorg. De test wordt opgenomen in diverse FMS-richtlijnen voor monitoring na bariatrische chirurgie en bij inflammatoire darmziekten. Ook wordt zink gebruikt in behandelrichtlijnen voor specifieke aandoeningen zoals ulcus cruris venosum. De klinische betekenis van zinktekort en -overschot is goed onderbouwd.

Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Often within a few working days. How soon you can be seen depends on how busy the location is and the type of analysis. For specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.

“Hele fijne en snelle service”
Hele fijne en snelle service! Ik contacteerde ze ‘s nachts omdat ik zsm moest bloedprikken, ik kon die ochtend nog terecht en heb dezelfde dag mijn uitslag binnengekregen. Echt top!!
“Bloedcheckup levert”
Waar ziekenhuizen moeilijk doen om checkup te doen , komt Bloedcheckup naar boven drijven als vertrouwde partner op gebied van gezondheid. Ik ben uiterst tevreden met bloed checkup
“Klantenservice was erg behulpzaam in…”
Klantenservice was erg behulpzaam in het beantwoorden van mijn vragen. Ik had ook een extra setje buizen nodig als back-up en dat was geen probleem. Ik had een groot test panel besteld, maar de resultaten waren binnen 1 week binnen. Rapport zag er netjes uit.
“Snelle en goede service”
Je hebt de spullen snel in huis en het is duidelijk wat je daarna moet doen. Ook de uitslag heb je snel in huis, ik dezelfde avond al de eerste uitslagen. Bij een bepaling ging het fout, niet eens door het bedrijf maar door het bloedafname punt en die bepaling kreeg ik gewoon vergoed, ook het geld terug stond erg snel op mijn rekening. Vragen worden ook snel beantwoord dus al met al een positieve ervaring bij Bloedcheckup.nl
“Fijn bedrijf met geweldig veel opties…”
Fijn bedrijf met geweldig veel opties om zelfstandig je gezondheid in het oog te houden, als sporter een must want de dokters hebben toch geen verstand van wat relevant en anders is voor sport. Ook zeer tevreden over Stijn zelf! Aangename kerel en goed bereikbaar voor vragen en hulp tijdens bestellen :D
“My experience was very positive”
My experience was very positive. I needed to pass several very specific tests. They provide 24/7 customer support. They were friendly and prompt.
“Top!”
Snelle en makkelijke afhandeling. Duidelijke instructies en binnen anderhalve dag al resultaat binnen. Top service!
“Amazing service!”
Received a packet with everything needed, went to a walk in clinic (Amsterdam DC Clinic) where my blood was drawn and I was out the door within 5 minutes, and then after posting the samples, received results 2 days later. Results were easy to understand as well. Amazing service, would highly recommend!
