About PSA testing: screening vs. indication

PSA testing is not recommended by the Dutch College of General Practitioners (NHG) or the Health Council as screening in men without complaints. The test can lead to follow-up tests and treatment for findings that would not have posed a clinical problem (overtreatment).

The test is however useful for specific indications: urinary complaints (LUTS), a previously elevated PSA value, or a familial background of prostate cancer. Please discuss the wish for this test with your GP first so results and next steps can be properly integrated.

Source: guidelines from the NHG and advice from the Health Council of the Netherlands on PSA testing and prostate cancer screening.

What is the Testosterone Replacement Therapy (TRT) Blood Test?

The TRT Blood Test is a comprehensive blood analysis specifically developed to check if you could benefit from testosterone replacement therapy. This test measures not only your testosterone levels, but also important hormones that regulate testosterone production, as well as markers for liver, and blood. It is essential for men with symptoms of low testosterone such as fatigue, decreased libido, mood swings, and loss of muscle mass. If suitable, a physician can directly prescribe and guide TRT.

What is tested?

  • Testosterone (total) – The primary male sex hormone
  • LH (Luteinizing hormone) – Hormone that stimulates testosterone production in the testes
  • FSH (Follicle-stimulating hormone) – Regulates sperm production
  • Estradiol – Main estrogen, converted from testosterone
  • Prolactin – Hormone that can inhibit testosterone production at elevated levels
  • Hemoglobin – Oxygen-transporting protein in red blood cells
  • Hematocrit (Ht) – Percentage of red blood cells in blood
  • ALT (Alanine transaminase) – Liver enzyme
  • AST (Aspartate transaminase) – Liver enzyme
  • Gamma-GT – Liver enzyme for bile duct function
  • Alkaline phosphatase – Enzyme for liver and bone health

Why should you get the TRT Blood Test?

This test is crucial for men considering starting TRT or those already using TRT and wishing to monitor their levels. Symptoms of low testosterone such as chronic fatigue, decreased libido, erectile dysfunction, loss of muscle mass, increase in body fat, and depressive feelings can significantly reduce quality of life. The test provides a complete picture of your hormonal status and checks important safety markers such as liver function, and blood counts that are important for TRT treatment.

What does it indicate?

The results provide comprehensive insight into your hormonal health and suitability for TRT. This test measures:

  • Testosterone levels and regulation – Low testosterone with low LH/FSH indicates secondary hypogonadism (brain), low testosterone with high LH/FSH indicates primary hypogonadism (testes)
  • Estradiol – Elevated levels can cause side effects
  • Liver and blood values – Important for safe treatment

This information helps physicians develop a personalized TRT plan with optimal dosage and monitoring.

What does a high level mean?

  • High testosterone levels during TRT – May indicate an excessively high dosage
  • Elevated hematocrit – A known side effect of TRT that increases the risk of blood clots
  • Elevated liver enzymes – May indicate liver strain
  • Elevated estradiol – Can lead to fluid retention, gynecomastia, and mood swings

These values help to safely optimize treatment.

What does a low level mean?

  • Low testosterone levels – Confirm the diagnosis of hypogonadism and justify TRT treatment
  • Low LH/FSH with low testosterone – Indicate a problem in the pituitary or hypothalamus
  • Too low hematocrit during TRT – May indicate anemia
  • Low estradiol – Can lead to joint problems and decreased bone density

This information helps physicians develop a personalized TRT plan with optimal dosage and monitoring.

Indication-specific evidence

This test has clinical value for specific complaints or indications, but is not intended as screening without symptoms.

Rationale for this test

Deze bloedtest meet hormonen en veiligheidsmarkers die relevant zijn voor testosteron replacement therapie (TRT). TRT zelf is een gevestigde behandeling binnen de reguliere geneeskunde voor mannen met bewezen hypogonadisme (testosterontekort). De test is echter niet bedoeld als screening zonder klachten of medische indicatie. Voor het starten van TRT is altijd medische begeleiding noodzakelijk, inclusief grondige diagnostiek en afweging van risico's zoals cardiovasculaire effecten en prostaatgezondheid.

Practical information

Frequently asked questions

How does it work from order to result?

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.

How quickly can I get tested?

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.

Do I need to book an appointment?

At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

Do I need to fast before the test?

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.

When and how do I receive my result?

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 receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.

Where can I go for collection?

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.

“Very happy to have found this business”

Very happy to have found this business. We need to check our blood more often :) The process was easy. They sent me the kit at home, then I had to go to a clinic with the papers and they knew what they had to do. I got the results in less than a week.

DenisaVerified

“Smooth process and good support”

Amazing website experience. I ordered various tests for 2 people. We went to one of the supported centers and took samples. Also after the results were ready, I needed a letter from the laboratory and they prepared the letter for me in no time. Definitely recommended.

Majid HajiheidariVerified

“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!

Trudi CoetzeeVerified

“Great customer service”

I ordered a test through bloedcheckup.nl but later realized I no longer needed it. I contacted their support team, and they were very quick, responsive, and helpful in handling my cancellation. The whole process was smooth and efficient. Great customer service!
