I am an analyst at a CRO, I need advice on an incident. I'm thinking of bringing it up to my manager or our director but I need the scientists referral when I want to quit this job.

Basically I biotinylated a test item last Thursday and the daily work instructions were wrong. The scientist had me dilute the biotin-TI above the standard curve so it couldn't be quantified. I noticed after the run and called him to tell him his mistake. The next day he corrects it and signs the footnote 2 days ahead so it looks like I didn't follow the instructions rather than it being his fuck up.

I have proof that he did that in that I had already made a correction on that page and signed the day the run performed under "A" but the time traveller signed a day early as "B".

What tilts me the most is on the reanalysis he hands me the same dilution factors but with different values so I could fuck up the run twice if I hadn't spotted it.

WWYD?
