hepatitis c

[mamae62]

what does is mean when your hcv log 10 is a 6.7 and the hep c quantitation is 5,162,590

Hello, have you talked to your doctor regarding treatment for Hepatitis C?
Good luck, many people are so supportive  here.

That is actually a log drop calculator that is used during treatment to assess response to treatment.

     VL                log 10

5,250,000           6.720

It means you have a viral load of 5,162,590, the log 10 is basically the same number expressed in a different form

Your viral load is the amount of specific viruses that you have, in a given volume of your blood (usually 1 milliliter = 1 cubic centimeter). More precisely, it means that the amount of Hep C genetic material found in your blood corresponds to as many Hep C viruses as the given number says. Therefore the given number denotes "viral equivalents."

Logarthmic format

Now, recently some people express these numbers also in logarithmic form (logarithmic transformed number).

log(1730000)=6.24

6.24 is the logarithmic transformed number of the viral load of our above example. A result of 3.5 for a viral load, that someone reported, seems to be such a number (unless he forgot to write down a "10" and an exponent). You need a calculator to convert this. You have to use the function 10x , where you have to replace x with the logarithmic number, in the above case 3.5. The result would be: 103.5 = 3162 virus equivalents per milliliter.

When you take the logarithmic number from the first example, 6.24, you have to calculate 106.24 = 1730000 , and here we have the original number of virus equivalents again. If you don't have a calculator, you can estimate the order of magnitude of a viral load expressed as a logarithmic number. From the logarithmic number, you take the first digit (left of the point) and add 1 to this number. This gives you the number of digits that your viral load has (expressed as a plain number).

Example: Logarithmic number 6.24

Left of the point is "6". 6+1 = 7

The number that gives the viral load is 7 digits long, that means it is between 1,000,000 and 9,999,999 (digit # 1 234 567)

The next digit (right of the point of the logarithmic number) shows whether you are high or low in the range.

In case you have a logarithmic number *and* a blood volume other than 1 ml, you have to convert the logarithmic number to a plain number *first*, and then correct it to correspond to 1 ml !

Therefore it is important to have a close look at your lab report and see in what units the result is given!
