Help: Unit conversion

Postby Dr.Stein » Sat Dec 30, 2006 3:20 am

Please help this old lady to convert from ng/dL to ng/mL :oops: :oops:

For instance, my sample contains testosterone as much as 300 ng/dL. If the unit is changed for ng/mL, how much it will be?

Or simply, could you tell me please 1 ng/dL = ... ng/mL or 1 ng/mL = ... ng/dL whatever :)

This problem occured when I have to compare two methods of hormone measurement. Using RIA method, the unit is ng/ml, which the maximum calibrator contains testosterone 1,600 ng/dl. While for ELISA method, the maximum testosterone can be detected is 18 ng/mL.

I should know which method I should apply for my research. Thank you ;)

Dear, Doc........(Fit), Hope You are Fit and Fine too. :P

1dL=100mL
1ng/dl=0.01ng/mL
1ng/mL=100ng/dL

300ng/dL=3ng/mL :)

So ELISA detects 18ng/mL i.e. 1800ng/dL :P
and RIA detects 16ng/ml i.e 1600ng/dL

So ELISA is Best suited... :P

Nowadays you are so busy.... :( That you appear rare to me... :cry:

Aha! Thank you very much, my dear. You know I am very bad dealing with numbers :oops: :oops:

Well, now is the second step: calculating fund and advantage-disadvantage :roll: It is not a must for you to help me again, but if you will do that for me I will be the most happiest person in the world now :) In the future I would like to offer you to be my private assistant and promote you for my private accountant :lol:

I applied RIA few times ago. The 100-tubes kit costs US$200 and I have to pay US$2 per tube for gamma counter counting. Plus 4 extra tubes for controls. I need to apply that twice, thus total fee will be... pfff... :cry:

I have no idea with ELISA yet. But after browsing here and there, the 96-wells kit costs US$300 or more. However, it seems that I just need one step to read the result: ELISA reader can read all 96 wells at one time. Much cheaper than US$2 x 100 x 2 I think but I have to make sure about this and hey I need 2 kits too aww :roll:

I think I can't sleep tonite :(

Ok. If you are using 100 tubes including 4 control then 2 kits will be required for 2 sets.

so.... US$200x2=US$400......... gamma count US$200x2=US$400...
so total 400+400=US$800. :?

800 US Dollar(s) = 7194239 Indonesian Rupiah(s) :shock:

If you do not include 4 control in 100 tubes then 1 extra kit will be required for that; and cost will be more and depend upon wheather you have to buy full 100 tube kit or small kit is available...

So in ELISA your cost comes to US$600 for 2 sets and add ELISA reader cost if aplicable... so if reader is not going to cost any more then you can go for ELISA as cost is lower than RIA. :P

Unfortunately, the control doesn't include in the kit package :( I have to buy it separately and the package contains minimum 100 tubes though I just need 4 tubes :evil:

*pull out her hairs*

:cry:


BTW, thank you for all your help, Sach :)
