Brain Natriuretic Peptide (BNP) is a hormone primarily produced by the cardiac muscles in response to stretching. BNP levels in the blood increase when the heart has to work harder. It is often measured to diagnose heart failure or assess its severity, as higher BNP levels may indicate an increased workload on the heart.
Testing for BNP is useful for assessing the presence and severity of heart failure. It can help distinguish heart failure from other conditions with similar symptoms, such as pulmonary disorders. BNP testing is also valuable for monitoring the effectiveness of treatments for heart failure.
An elevated BNP level in the blood suggests that the heart is under pressure and may not be working efficiently, which can be a sign of heart failure. The BNP test can also help determine the risk of future cardiac problems in people without symptoms.
A high BNP level usually indicates heart failure or another condition that puts extra strain on the heart. It can also be elevated in cases of kidney failure, because the kidneys are less efficient at removing BNP from the blood.
A low BNP level is usually an indication that heart failure is less likely to be the cause of a patient's symptoms. It may indicate effective treatment or the absence of significant cardiac strain.
Pro-BNP, NT- (brain natriuretic propeptide)
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Deze test is een gevestigde marker voor de diagnostiek en beoordeling van hartfalen binnen de Nederlandse reguliere geneeskunde. De klinische betekenis van BNP en NT-proBNP is goed onderbouwd in wetenschappelijke literatuur en wordt breed toegepast in de cardiologische praktijk voor het uitsluiten of bevestigen van hartfalen bij patiënten met klachten zoals kortademigheid.

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.

“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 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.

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!
