Lactate, also known as lactic acid, is a chemical substance that naturally occurs in the body as a byproduct of anaerobic metabolism, the process in which energy is produced without oxygen. When your body requires more energy than it can supply through normal, oxygen-dependent processes, such as during intensive exertion, it produces lactate.
Testing lactate levels can be useful for assessing how well your body utilizes oxygen during exertion and for identifying the presence of certain medical conditions, such as lactic acidosis. It can also help in determining the appropriate training level for athletes.
Blood lactate levels can provide insight into the balance between oxygen demand and supply in the body. It assists in diagnosing lactic acidosis, a condition where lactate accumulates in the body and lowers the blood pH level, which can indicate issues such as oxygen deficiency in the body.
A high lactate level may indicate lactic acidosis, which can point to underlying issues such as heart failure, kidney failure, or severe infections. It can also result from physical overexertion, particularly in athletes.
A low lactate level is generally not concerning and may indicate that your body produces energy efficiently and handles the oxygen it utilizes well.
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Lactaat is een gevestigde laboratoriumtest binnen de Nederlandse reguliere geneeskunde. De test wordt gebruikt in diverse klinische situaties zoals de diagnostiek van bacteriële meningitis, acuut leverfalen, metabole stoornissen bij kinderen, en bij de beoordeling van weefselhypoxie. De klinische betekenis en diagnostische waarde zijn goed onderbouwd in Nederlandse zorgrichtlijnen.

Public-facing website of the Dutch Society for Clinical Chemistry with explanations of blood tests and laboratory values.
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…”
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

“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!
