Default Deming Regression for labs

Does anyone know of a excel add-on or FREE software that includes the
Deming regression?

My hospital lab is part of a multi-hospital system, but they do not
want to buy software for each lab. Our lab director thinks there is
only one person that has the software (EP Evaluator) to do all the
calculations for lot to lot, normal range verification, etc.. at the
flagship hospital lab. We should not have to wait 2-3 weeks for them
to do our statistics when it could be done in an hour or so.

I do not want to use my money to buy Analyse-it or EP Evaluator if I
can avoid it. I know EP has an online version, but then again it costs
$1 dollar per page. I can pretty much do everything I need in excel
except for the Deming regression. I have searched the internet for a
free add-on to no avail. Any help would be appreciated.

Here is a chapter from a book with a simple Excel macro that calculates
Deming slope and intercept.
