Is this the same as a milk allergy test?

No. Lactose intolerance is a digestive issue. Milk allergy is an immune-system response and is evaluated differently.

Why can this not be done at a regular draw site?

Quest states this cannot be performed at a standard patient service center because the lactol solution requires on-site preparation.

Yes. Quest states no food or drink other than water for at least 8 hours before testing.

No. This version uses timed blood glucose measurements after a lactose drink. Hydrogen breath testing is another method clinicians may use.
