Hello expert,
I am writing new SOP for cleaning validation. When it comes to Certain allergenic ingredients and highly potent material, Some guidelines recommend that residue should be undetectable by best analytical method.
Suppose that in our semi-solid line, we manufacture 10 products which contain corticosteroid. Do we need to carry out cleaning validation for all 10 products to assure all API residues are below LOD or we only need to find out 1 worst-case product for validation?
Thank you.
