Thank you for your inquiry.
There is no “guideline” for skin testing to this product, but there are two reports in the literature (1, 2) where skin testing to Intralipid has been described. In Reference Number 1 only prick tests were done to the “neat” preparation. However, in Reference Number 2, both epicutaneous and intracutaneous tests were done. Both of these references are available to you online at no charge. I have copied for you below the link to each reference.
In Reference Number 2, skin prick testing was done to a concentration of 100 mg/mL of Intralipid, and intradermal tests were done using concentrations of 1, 10, and 100 mg/mL.
In both of the studies reported, tests were negative.
Thank you again for your inquiry and we hope this response is helpful to you.
