HDL stands for High-Density Lipoprotein. This type of cholesterol is known as 'good' cholesterol. HDL cholesterol helps to remove excess cholesterol from the blood vessels and return it to the liver, where it is broken down and removed from the body. This reduces the risk of cardiovascular diseases.
Measuring HDL cholesterol is important for assessing your risk of cardiovascular disease. An HDL test is often part of a lipid panel, a series of tests to measure the amount of cholesterol and other fats in your blood.
HDL cholesterol levels provide insight into how well your body is able to process and remove cholesterol. Higher levels of HDL cholesterol are associated with a lower risk of heart disease, whereas lower levels may indicate a higher risk.
A high HDL cholesterol level is generally considered favorable and may offer protection against cardiovascular disease. It means that your body is effectively removing cholesterol from the blood vessels.
A low HDL cholesterol level is considered a risk factor for cardiovascular disease. It suggests that there is not enough 'good' cholesterol to remove excess cholesterol from the blood vessels, which can lead to the build-up of plaque and ultimately to heart disease.
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
HDL-cholesterol is een standaard-bepaling in Nederlandse zorgrichtlijnen voor cardiovasculair risicomanagement. De test wordt gebruikt om het risico op hart- en vaatziekten in te schatten en is onderdeel van het lipidenprofiel dat in de reguliere zorg wordt ingezet. De klinische betekenis van HDL-cholesterol als beschermende fractie is goed onderbouwd.

Brochure on preventive health checks: careful choice, reliability, pros and cons, checklist.

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! 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!
