What are Log Counts???

[niknak67]

Math was never my strength....I am confused by these log counts that everyone is talking about...and the meaning behind them....

If you started with 2.8 million what should you have achieved by week 4???

Ahh! some real expertise back on the site! hey bill

Hi gents!

[can-do-man]

As you can see from your prior post your viral load at week 3 was 18215 so your log drop was just slighty better then 2, still don't agree with what your doctor did but i have my doubts that in 6 days you would have made it to 1000 which is when the futility rules kick in.

gee everyone just wake up??   Hey Bill ..good to see ya!

Logarithms is just a different way that Viral load is expressed. If you go to this  converter  and put in the base of 10 you will get VL.
If you put in your viral load (logarithmic number in( a )  and always a base of 10 (b) then  the exponet(x) will give you the viral load in  log form

a (logarithmic number):  
b (base):  
x (exponent):

A log (logarithmic) result is an alternative to expressing viral load numerically. In your case, a viral load of 2.8 million (2,800,000) is equivalent to a ‘log’ value of  6.45. They both represent the same figure; however using log values is sometimes an easier way to manage large, cumbersome numbers and often give additional insight to treatment response.

One way to calculate log reduction simply is by removing a decimal place from the right column:

Baseline viral load of 2,800,000:

2,800,000
280,000 = 1 log reduction
28,000   = 2 log reduction
2,800     = 3 log reduction
etc.

You can also convert numerical expression to logarithmic expression by using a mathematical calculator; if you have a PC-

From the START menu, open ‘all programs’, open ‘accessories‘,

then open ‘calculator’

From the calculator, click on the ‘view’ tab at the top of the page, and be sure ‘scientific’ is selected rather than ‘standard. Then, enter the viral load ‘2,800,000’, and click on the ‘log’ button. This should convert the viral load to logarithmic format, and you’ll see it’s now 6.447158..... just round up and there’s your answer.

I believe some treatment drugs now have specific treatment ‘futility’ parameters; best to check with your physician to see what they expect now. Or perhaps another member here might have this data for you if you specify your treatment regimen.

Good luck and take care-

2,800,000 for every log drop take one zero off the end. 1 log drop you would be at 280,000 A two log drop would mean 28,000 and so on.

If your on incivek your needing at least close to a 4 log drop to go on..... Good luck

Check out the link below, welcome but I'm bad at math too.lol  At least this will bump you up.
