Guest guest Posted September 16, 2004 Report Share Posted September 16, 2004 Can anyone help me to convert PG/ML to NG/DL? I just got my latest B/T results and it looks like I had a sudden drop in free T. It's always been ~ 2% and the lab range given was always (47 -244 pg/ml). These are my latest results: Total T 772 (241 – 827) NG/DL Free T 15.8 (20 – 76 ) PG/ML Percent free 0.2 % LH 5.6 (2 – 18) MIU/ML E2 22 (21 – 50) PG/ML And those idiots at the lab forgot to do SHBG, but it's always been in the Range 22 – 30. I'd like to convert pg/ml to ng/dl and compute %free T, because I do not unsderstand `Percent free 0.2' means 0.2% or 2%. Thanks Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 16, 2004 Report Share Posted September 16, 2004 Yeah, I think the factor you need is 0.1 based on a back of the envelope calc. You can double-check my work. 1 pg = 0.001 ng 1 ml = 0.01 dl 1 pg/ml = 0.001/0.01 ng/dl = 0.1 ng/dl 15.8 pg/ml = 1.58 ng/dl 1.58 / 772 = 0.002 Or 0.2% as your paperwork indicates See: http://www.simetric.co.uk/siprefix.htm for prefixes Brad > Can anyone help me to convert PG/ML to NG/DL? > > I just got my latest B/T results and it looks like I had a sudden > drop in free T. > It's always been ~ 2% and the lab range given was always (47 -244 > pg/ml). > > These are my latest results: > Total T 772 (241 – 827) NG/DL > Free T 15.8 (20 – 76 ) PG/ML > Percent free 0.2 % > LH 5.6 (2 – 18) MIU/ML > E2 22 (21 – 50) PG/ML > > And those idiots at the lab forgot to do SHBG, but it's always been > in the Range 22 – 30. > > I'd like to convert pg/ml to ng/dl and compute %free T, because I do > not unsderstand > `Percent free 0.2' means 0.2% or 2%. > > Thanks > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 16, 2004 Report Share Posted September 16, 2004 It just occured to me, if Brad's calculations are right, then how come the lab range for free T is 9.5 - 43 pg/ml? According to the formula, the max lab range would be .05%. And I know for sure that free T is supposed to be ~ 2% of total. May be it is not that simple as just mathematical conversion? Any comments will be much appreciated. > > Can anyone help me to convert PG/ML to NG/DL? > > > > I just got my latest B/T results and it looks like I had a sudden > > drop in free T. > > It's always been ~ 2% and the lab range given was always (47 -244 > > pg/ml). > > > > These are my latest results: > > Total T 772 (241 – 827) NG/DL > > Free T 15.8 (20 – 76 ) PG/ML > > Percent free 0.2 % > > LH 5.6 (2 – 18) MIU/ML > > E2 22 (21 – 50) PG/ML > > > > And those idiots at the lab forgot to do SHBG, but it's always been > > in the Range 22 – 30. > > > > I'd like to convert pg/ml to ng/dl and compute %free T, because I do > > not unsderstand > > `Percent free 0.2' means 0.2% or 2%. > > > > Thanks > > Quote Link to comment Share on other sites More sharing options...

That's not the range you cited before. It was 20 - 76. The lab range on a percentage basis would be: Low 2 / 827 = 0.0024 = 0.24% High 7.6 / 241 = 0.0315 = 3.15% Brad >According to the formula, the max lab range would be .05%. >And I know for sure that free T is supposed to be ~ 2% of total. >May be it is not that simple as just mathematical conversion? >Any comments will be much appreciated. > Quote Link to comment Share on other sites More sharing options...
