Estradiol, also known as 17-beta-estradiol (17 beta estradiol) or E2, is an essential hormone found in both men and women. As the most active form of estrogen, it plays a crucial role in various bodily functions, including hormonal balance, bone health, and reproductive functions. Also known as estradiol, estrogen or oestrogen.
Measuring estradiol levels is important for diagnosing hormonal imbalance and monitoring reproductive health. The test is used for fertility issues, monitoring hormone therapies, and evaluating symptoms that may indicate hormonal disorders.
In women: useful for menstrual cycle problems, fertility issues, menopause symptoms, hormone therapy monitoring, and evaluation of ovarian function.
In men: useful for reduced libido, erectile dysfunction, gynecomastia (breast development), fertility investigation, and hormone therapy monitoring.
Estradiol levels provide insight into hormonal balance and may indicate various conditions. Deviations can point to problems with the gonads, liver disorders, or exposure to external hormones.
In women: may indicate pregnancy, or ovarian hyperstimulation.
In men: may lead to gynecomastia and emotional instability, and may indicate liver disease, or the effect of certain medications.
In women: may indicate reduced ovarian function, early menopause, or fertility problems.
In men: may indicate reduced gonadal function, pituitary problems, osteoporosis, or increased risk of bone fractures in older men.

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.

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

“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!
