About PSA testing: screening vs. indication
The Supplemental TRT blood test is the most comprehensive and advanced TRT monitoring available. This test adds advanced hormonal markers, thyroid function, complete blood count with differentiation, inflammatory markers, and additional cardiovascular risk factors. It is the ultimate test for men who want maximum insight into their hormonal health during TRT, in complex cases, or when standard TRT monitoring does not adequately explain symptoms. This test is recommended for persistent symptoms despite TRT, suspected coexisting conditions, or for men seeking optimal health.
This most comprehensive TRT test is suitable when standard TRT monitoring is insufficient, for persistent symptoms despite optimal testosterone levels, in complex hormonal problems, or for optimal health monitoring. DHEA-S provides insight into adrenal function. Complete thyroid function (TSH, fT4, fT3) is crucial because thyroid problems can limit TRT effectiveness. HbA1c and insulin monitor metabolic health because TRT can affect insulin sensitivity. hs-CRP measures systemic inflammation. Vitamin D and ferritin are important for optimal TRT response. This comprehensive package is recommended at the start of complex TRT trajectories, for unexplained symptoms, or for men who want to preventively optimize all aspects of their health.
The results provide the most complete picture of your hormonal and metabolic health during TRT. In addition to all standard TRT markers, adrenal function (DHEA-S), thyroid function (complete analysis), metabolic health (glucose, HbA1c, insulin), inflammatory status (hs-CRP), nutritional status (vitamin D, ferritin), and advanced cardiovascular markers (Apo B, non-HDL) are also measured. This helps explain why some men respond optimally to TRT while others still experience symptoms despite good testosterone levels. Often, coexisting conditions such as hypothyroidism, adrenal fatigue, insulin resistance, or vitamin deficiencies are the explanation.
Elevated testosterone requires dose reduction. Very high hematocrit (above 54%) is dangerous and requires immediate intervention. Elevated estradiol can be treated with aromatase inhibitors. Elevated PSA (especially elevated PSA/free PSA ratio) requires urological evaluation. High DHEA-S can indicate adrenal conditions. Elevated thyroid function (low TSH, high fT4/fT3) can worsen TRT side effects. Elevated HbA1c and insulin indicate insulin resistance or diabetes. High hs-CRP indicates systemic inflammation. High Apo B indicates increased cardiovascular risk despite normal LDL. These comprehensive markers help optimize all aspects of health.
Low testosterone during TRT requires dose increase. Low DHEA-S can indicate adrenal fatigue which limits TRT effectiveness and may require supplementation. Low thyroid function (high TSH, low fT4/fT3) explains persistent fatigue despite optimal testosterone levels and requires thyroid treatment. Low vitamin D limits TRT response and bone health. Low ferritin can explain fatigue. Low HDL and high Apo B increase cardiovascular risk. This complete analysis helps identify and optimize all factors for maximum TRT effectiveness and overall health. It is the gold standard for complex TRT monitoring and preventive healthcare.

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 has clinical value for specific complaints or indications, but is not intended as screening without symptoms.
Rationale for this test
Deze uitgebreide bloedtest combineert meerdere standaard-bepalingen die in Nederlandse zorgrichtlijnen worden gebruikt voor monitoring van testosterontherapie en algemene gezondheid. De individuele markers (testosteron, schildklier, lipiden, glucose, HbA1c, leverfunctie, nierfunctie, bloedbeeld) zijn klinisch gevalideerd. Het pakket is echter niet bedoeld als screening zonder medische indicatie, maar voor monitoring tijdens testosteronbehandeling of bij specifieke klachten die duiden op hormonale problemen.
