Gut microbiome kit: ships once your add-on is confirmed and is typically delivered within 3 to 9 working days, depending on where you live. You return the sample yourself by post using the prepaid envelope.
Lucis home kit: shipped within about 24 hours and delivered in 3 to 5 business days, so it arrives roughly 3 to 6 working days after booking. You need it before your lab visit.
No kit ships to the UK or Portugal: all samples there are collected at the partner laboratory.
