Just thought some of you may be interested to know that I asked Blue Horizon if they use Biotin in their tests and they said no.

It isn't BH that actually does the tests, they send them out to labs.
My last BH tests were sent to The Doctor's Laboratory.
Originally they used County Pathology, who is used by Medichecks now, and I'm sure I saw it on the forum that someone asked and Medichecks said Biotin was used in the assay for their tests.
So it really depends on the lab doing the actual test and I don't know if BH use more than one lab for their tests.
I'm assuming they checked with whoever they use?
If they still use County Pathology for some of their tests then who is correct - Medichecks or BH? But like I say, I don't know if they use more than one lab now.
Their website says TDL pathology services so I'll try and contact them.
TDL is The Docor's Laboratory, so if they only use the one lab then I'm sure their answer is correct. My last return envelope to TDL was a silver/grey colour. I'm just a bit worried in case they do still use County Pathology like they used to, and CP's return envelopes used to be yellow, my last one was bright pink.
