The Lab Basic package is a general blood test that measures the most essential blood values for a complete picture of your health. This package tests the three most important organ systems: kidney function, liver function, and thyroid function. In addition, important electrolytes and blood values are checked. It is a recommended test as a regular check-up to get a full overview of your health, even if you do not have specific complaints.
This test is suitable for anyone who wants to perform a general health check. It is particularly useful for vague complaints like fatigue, when using medication that can burden organs, or as preventive screening. The test provides insight into how well your kidneys, liver, and thyroid are functioning. Abnormalities in these organs can lead to serious health problems if not detected in time. Electrolyte disturbances can also have significant consequences for the heart and muscles.
The results provide an overview of the function of your most important organs. Abnormal hemoglobin and MCV can indicate anemia or other blood disorders. TSH and fT4 show whether your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism). Creatinine and eGFR measure how well your kidneys filter waste products. ALT and AST provide insight into liver health. Sodium and potassium are crucial for fluid balance and heart function. Abnormalities often require further investigation or treatment.
Increased hemoglobin can indicate dehydration or hemoconcentration. High TSH with low fT4 indicates hypothyroidism (underactive thyroid). Elevated creatinine means reduced kidney function. Elevated liver enzymes (ALT/AST) can indicate liver inflammation, fatty liver, alcohol use, or medication side effects. High sodium can indicate dehydration, while high potassium is dangerous for the heart and requires immediate attention. These values should always be evaluated by a physician.
Low hemoglobin indicates anemia with associated fatigue and shortness of breath. Low MCV indicates iron-deficiency anemia. Low TSH with high fT4 means hyperthyroidism (overactive thyroid). Low electrolytes (sodium/potassium) can result from vomiting, diarrhea, or medication use and can lead to muscle weakness, cardiac arrhythmias, and confusion. Very low potassium is a medical emergency. These abnormalities usually require treatment to prevent serious complications.
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!
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Dit pakket bevat standaard laboratoriumbepalingen die in Nederlandse zorgrichtlijnen worden gebruikt voor diagnostiek bij diverse klachten en aandoeningen. De individuele tests (hemoglobine, TSH, fT4, kreatinine, eGFR, leverenzymen, elektrolyten) zijn gevestigde diagnostische middelen binnen de reguliere geneeskunde. De NHG erkent 'algemeen bloedonderzoek' als veelvoorkomende indicatie in de huisartsenpraktijk, met name bij vermoeidheid en niet-specifieke klachten.
