You can request a test kit to test a 24 hour urine on the hemopyrrollactamcomplex (HPU-test 24 hours urine). A 24 hour HPU test is more accurate than a morning urine, but we do not recommend a 24 hour test for children and young adults up to 18 years, if they are not chronically ill or do not have to go to the toilet at night. A midstream morning urine is sufficient in this case.
The set includes a 3.2 liter brown collecting container with a preservative, an instruction and explanation, a urine tube, a transfer pipette and a laboratory request sheet. In the tube is a preservative that makes sure that the urine sample has a shelf live for 10 days at room temperature. One week prior to the test you may not take vitamin B6, multivitamin or pyridoxal-5-phosphate or high dose of zinc (over 50 mg). After you have filled the tube with urine, you can send it back to the address indicated. Within two weeks, you will be informed whether hemopyrrollactam is found in your urine and how much.
The original HPU-test, indicated by the registered mark ® for a 24 hour urine costs € 65.50. If you do not have a medical doctor or GP on the application form, you need to pay 21% VAT. The test costs than € 79.26. For all 24-hour tests your have to pay € 7.50 shipping fee.
– With extended use of vitamin B6 or pyridoxal-5-phosphate of 50 mg or more per day, the test will be false-negative. Even if you have left it out for several days, the value should be corrected for the amount of vitamin B6 used.
– You should not collect the urine after a long period of rest (for example a vacation).
– You should not collect the urine during or soon after a course of antibiotics.
– You should not collect the urine just after your menstruation; wait at least 4 days.
– During the test don’t use large amounts of alcoholic beverages.
– Don’t make the test shortly after an iron-drip. The test will be negative.
– When the container is not large enough, you can use another receiver or clean bucket. Pour the total content of the brown collection bottle in the bucket when the container is nearly full. The brown container you can use to determine the total volume.
