I've never done a mishap physical... but I can tell you this, it's all about the form number. If it's the same form number ie. 2807 & 2808 then it works, as long as it's within the time range required. Usually the extra testing, blood and urine, are just added to the main physical... the "meat and potatos" so to say. The Navy typically only has a few different phyical paperwork, all based either around sutibility/oversea physicals and flight physicals.
If you get down to specifics, I could probably answer a little better.
