3-scan mystery/uptake question

[Guest guest]

Dear and other interested parties,

Well, I have re-learned a very valuable lesson from my

school days and that is to always confirm the UNITS!

Yesterday (happy belated V-day, everyone!) I got 70

MICRO-curies of I-131 for measuring the uptake. The

technician said 1 micro-curie is 1/1000th of a

millicurie. Today I got the actual scan dose of 2

millicuries of I-131. So, no worries about stunning! I

do the scan on Monday.

Thanks very much to everyone who posted to say how

weird my schedule sounded because it made me ask

questions I wouldn't have otherwise.

I also have a question about the uptake. The last time

I did this two years ago, they measured it at 6

percent (after a TT). Today they measured it as 0

percent. The technician even did it a second time just

to make sure and it came out as 61 counts which she

said they consider as 0 percent. I said that's good,

right? She said yes.

My question is, does the uptake result have any

bearing on what my scan results might be?
