What is Magnesium?
Magnesium is an essential mineral that plays a crucial role in hundreds of biochemical reactions in the human body. It helps regulate muscle and nerve function, blood glucose levels, blood pressure, and is involved in making protein, bone, and DNA.
Why test for Magnesium?
Testing for magnesium is useful for determining whether there is a magnesium deficiency or surplus in the body, both of which can cause health issues. It can be particularly useful for people with certain health conditions, such as kidney disease, or for people experiencing symptoms indicative of a magnesium deficiency or surplus.
What does it indicate?
Magnesium levels in urine provide an indication of how the body absorbs, uses, and excretes magnesium. This can aid in diagnosing abnormal magnesium levels that may point to various health problems.
What does a high magnesium level mean?
A high magnesium level in the urine may indicate excessive intake of magnesium through diet or supplements, or it may be an indication of reduced kidney function, where the body struggles to excrete magnesium.
What does a low magnesium level mean?
A low magnesium level may indicate a deficiency of this mineral, which can lead to various health problems such as muscle cramps, fatigue, and heart rhythm disorders. It can be caused by insufficient intake through diet, increased loss of magnesium through the kidneys, or an issue with the absorption of magnesium in the intestinal tract.
Limited evidence in mainstream medicine
The scientific support for this test within mainstream Dutch healthcare is limited. The test is not included in NHG/FMS standard guidelines.
Rationale for this test
Magnesium in urine wordt binnen de Nederlandse reguliere zorg niet gebruikt als standaard-diagnosticum voor magnesiumstatus. Urine-magnesium correleert niet betrouwbaar met de magnesiumvoorraad in het lichaam door de grote variatie in nierfunctie en uitscheiding. Voor het vaststellen van magnesiumtekort of -overschot wordt in de klinische praktijk bij voorkeur serum-magnesium bepaald, eventueel aangevuld met andere methoden bij specifieke indicaties.

Practical information
Frequently asked questions
How does the urine test work from A to Z?
After ordering we ship the collection kit to your home. You collect urine following the instructions, return it in the envelope, and receive your result digitally by email.
How do I collect my urine sample correctly?
Follow the included instructions, usually the midstream method in a sterile container. Pay attention to the right timing (first morning urine or random, depending on the test).
Do I need to avoid anything before collection?
For some tests yes (e.g. certain foods or supplements). Whether this applies is stated in the instructions. Read them before you start.
When and how do I receive my result?
Usually 2 to 5 working days after the lab receives your sample. You receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.
How do I return the collection materials to the lab?
Use the supplied return envelope and place it in the letter-mail bag inside a PostNL service point yourself as soon as possible. Do not hand it to counter staff or request track & trace. The instructions supplied with your test state when it must be sent.
What if I have questions or something doesn't work?
Feel free to contact us via WhatsApp, email or phone. We're happy to help you before, during or after your test. If the collection doesn't work, we'll arrange a solution or send new materials — no hassle.

I received a referral by email, just like from a GP. I did not have to send anything by post and could quickly visit a local blood collection centre. The results were fast and clear. The price was good, not too expensive, and all messages were secure.

“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.

“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.

“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!

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!
