But, IIRC the blood test is more accurate than the breathalizer.
Now THAT goes either way.
Either the breath test was marginal, so they wanted the blood test to seal the deal (charge of DUI), or
he failed it and they wanted a more accurate reading to possibly up the ante (Aggravated DUI?).
In other words, the blood test may show a higher concentration than the breath test.
Hope it's his first offense, if in fact he was "impaired".

I think in your OP you said he was "agitated" at the scene?
Did he give the cops a hard time?
If so, that's not good at all.
Best of luck.
