Order Guidelines/Laboratory Info
- Once you have paid for the test you will receive a confirmation email
- Testing laboratory - Biolab Medical Unit are based in the West End of London and they specialise in nutritional and environmental medicine offering a wide range of tests and a test referral service (for their website please click here)
- Test kit delivery - Test kits ordered before 3pm Monday to Friday will be sent out the same day. Test kits ordered after 3pm Monday to Thursday will be sent out the following day morning time. Test kits ordered after 3pm Friday and over the course of the weekend will not be sent out till Monday morning the following week
- Sample collection/sending - The test kit is sent directly to you and the sample can be collected at home. The test kit comes with instructions on how to collect the sample and comes with the relevant packaging for you to send it back to the laboratory. Once the sample has been collected you need to post the kit back to Biolab. Normal postal charges will apply (large letter rates UK). It is advised to send the sample at the start of the week so that the laboratory receives it during the same working week
- Please note: You can only order this test within Europe
- Refunds - Refunds are only possible if the test kit is unused and no samples have been sent to Biolab. If a refund is required then please email - orders@mindovermetal.co.uk, someone will then be in contact to process your refund
- Results - The test result is sent directly to you from mindovermetal Ltd and not from Biolab. The result is sent to the email that you provide when you place your order. Test results will come with an email from mindovermetal Ltd summarising your result reading. The test result is simple to understand and shows if you are above, below or within certain reference ranges. The turnaround time for results once the sample has reached the laboratory is 5 working days. Please make a note of the date you send the sample and if you do not receive your results within the time frame then please email orders@mindovermetal.co.uk and someone will be in contact
Description from Biolab
Iodine is required in small amounts by humans, the current RDA being 150 micrograms per day; the only known function of iodine in man is as a component of the secretions of the thyroid gland, principally tri-iodothyronine and thyroxine. Iodine is one of the halogen series of elements (along with fluorine, chlorine and bromine); it was formerly used as an antiseptic, but is now regarded as too toxic for that purpose.
80 - 90% of the total serum iodine is incorporated into thyroxine, which is largely protein bound; the remainder (5 - 15%) of the serum iodine is in the form of iodide (the plasma inorganic iodide) and it is this fraction that is filtered at the glomerulus and passes into the formed urine. Regulation of body iodine does not occur via changes in the glomerular filtration rate (as occurs with other essential elements) but via iodine uptake into the thyroid gland.
A common method for correction of iodine deficiency is salt iodization - the addition of potassium iodate to salt for human and livestock consumption to give a concentration of c. 15 ppm of iodine - with the urinary iodine concentration as the principal indicator of effect. Measurement of thyroid size has a more limited role as an indicator because it reflects chronic rather than immediate iodine deficiency.
Urine creatinine can be co-analysed with iodine to correct for urine dilution in a short collection (6 hours, early morning urine or random urine collection). Expressed in this way, the reference interval for urine iodine is 0.16 - 0.42 mmol/mol creatinine.
