This might just be me, but can we have a picture, chart, or something on the home page of the forum that shows the conversion factor between US and  Metric equivalence to figure out post of BUN Creatinine readings between our countries?

You can find conversion factors http://www.globalrph.com/conv_si.htm  but I don't really understand how it could work.

Here is what I think is some standard guidance for Creatinine:

Quote
Men: 0.2-0.5 mg/dl (USA) 15-40 umol/L (International)
Women: 0.3-0.9mg/dl (USA)   25-70 umol/L (International)

So looking at this example the low end range for guys is either .2 mg/dl (USA) or 15 umol/L (International), which implies a conversion factor of 75 (.2 * 75 = 15)
But the high end implies a conversion factor of 80 (.5 x 80 = 40)

And then the conversion table gives 88.4 as the conversion factor.

I went over to Home Dialysis Central to ask Dr Agar What's the deal with these divergent creatinine measures ... wow! the more I look into this stuff the more I realize it is all just people's best guess and every number comes with a margin of error.

Well there has to be something to make a post more understandable for someone in the the US to understand what a reading in a post from New Zealand means as an example. That is what I mean. A 1.2 MG/DL has to mean something to someone in another country not using MG/DL or vise versa in the medical community when physicians across the world collaborate or medical issues.

Newbie caretaker, so I may not know what I am talking about :)
Caretaker for my elderly father who has his first and current graft in March, 2010.
Previously in-center hemodialysis in national chain, now doing NxStage home dialysis training.
End of September 2010: after twelve days of training, we were asked to start dialyzing on our own at home, reluctantly, we agreed.
If you are on HD, did you know that Rapid fluid removal (UF = ultrafiltration) during dialysis is associated with cardiovascular morbidity?  http://ihatedialysis.com/forum/index.php?topic=20596
We follow a modified version: UF limit = (weight in kg)  *  10 ml/kg/hr * (130 - age)/100

How do you know you are getting sufficient hemodialysis?  Know your HDP!  Scribner, B. H. and D. G. Oreopoulos (2002). "The Hemodialysis Product (HDP): A Better Index of Dialysis Adequacy than Kt/V." Dialysis & Transplantation 31(1).   http://www.therenalnetwork.org/qi/resources/HDP.pdf

Closer to what is neeeded, but a number range I think would be more beneficial here.

The following is a reproduction of a Google spreadsheet chart with the blue line and  blue numeral in µmole/L and red in mg/dL for the creatinine conversion.  The dates on the chart does not represent anything; it is not possible to embed Google chart in this forum.
