Hello Everyone,
A few weeks ago I received a positive result from a Biocard home celiac test. I then received a negative lab result (they only ran one test). I emailed the company to ask them about the different results. This is the response I received:
In clinical studies in the EU where the Biocard has been used and there has been a discrepancy between the equivalent Elisa lab test and the Biocard (Biocard “+” and Labe “-“), over time the “-“ lab tests become “+”. This has been explained by the sensitivity, specificity and cut-off limit of the Biocard relative to lab testing. The cutoff for the Biocard is 5u (international units). Many laboratory tests are between 10 and 20u.
So should I wait to see if I eventually get a positive blood test? Will my doctor even consider retesting? Should I just go ahead and try a gluten free diet?
I have an appointment with a Naturopathic Doctor next week. I'll see what she has to say.
Thanks for listening.
