How do I return a lab if I live outside of the US?Updated 7 months ago

To ensure that your lab is shipped correctly from outside of the US, please follow these instructions.                        

Due to each country having its own guidelines, it is best for all international clients to coordinate their own shipping and associated shipping costs when returning samples to the laboratory that is evaluating your lab test. As you will see below, each individual lab test is listed with the correct shipping address. 

Also, please note, if a USA domestic shipping label for the lab was included in the lab box, please discard and do not use that label. 

We recommend sending samples via 2nd day air using UPS or FedEx or choosing your country’s best shipping method to return the samples to the lab address as listed below. 

For The Following Tests:

  • Candida Metabolic & Vitamins Test – Urine Test
  • Environmental Toxicity Test – Urine Test
  • Food Sensitivity Test -Blood Spot Test
  • Mold Toxicity Test – Urine Test 

Specific Test Guidelines for These Tests:

  • Urine Test samples: you must FREEZE urine samples to maintain the integrity of the sample. Samples must reach the lab within 5 days of sending. We recommend priority 2-day shipping on a Monday or Tuesday to ensure that the sample arrives to the lab on a weekday to be processed (the lab does not access packages on weekend). 
  • Blood Spot samples: are viable for 21 days, after that period samples will be discarded, and recollection will be required.
