Question
What do my viral load test results mean?
5 January 2016. Related: All topics, CD4 and viral load.
Please can you explain how viral load results mean?
I got my results back and I don’t understand them. It says log units is 2.777 and my RNA copies is 599 cp/mL.
Is this low or high? My CD4 count is 697.
Answer
Hi
Thanks for your question – and it is good that you want to understand your test results.
Sometimes this can be dfficult if your doctor has not explained them clearly. It is also okay to ask your doctor or nurse to explain anything that you are not sure of.
Viral loads tests tells you how much virus is in a millilitre of blood (or another body fluid being measured).
When not on treatment, viral load can range from undetectable to several millions. For anyone on HIV treatment (ART), viral load should ideally get to undetectable, This is defined as being less than 50 copies/mL.
Your test results are the 599 copies/mL, so your viral load is still detectable at 599.
The ‘2.777 log units’ from your test results is a slightly complicated way of saying exactly the same thing as ‘599 copies/mL’.
Because viral loads have such a huge range of numbers they are sometimes expressed in ‘log units’ to make it easier to write them on graphs and diagrams. Doctors and scientists use log scales to look at changes to viral loads over time. See this table of log units compared to viral loads in copies/mL.
Whether this is considered high or low depends on whether or not you are on treatment.
- If you’re not on treatment yet this is a relatively low viral load, which is a good thing.
- If you are on treatment, then if you only recently started ART, your viral load might still be going down.
- If you have been on treatment for more than six month, please talk to your doctor about why the results in not undetectable.

If you tell me if you are currently on treatment or not I can provide more individual information, Also, if you are on treatment, when did you start?

Hi Kudzi,
This should mean local than detectable level, so less than 50 copies ml. It refers to a viral load test result.
What is the meaning of VL= LDL
Hi Kuldeep,
When someone has a viral load of less than 50 copies ml this means that their viral load is undetectable. Their HIV is 100% under control. You’re doing great.
My viral load below 20 copies/ml, what is my condition, I can’t understand. Plss reply
Hi Carol,
It’s great that your viral load has been undetectable for the past 3 years. And yes, undetectable on HIV treatment means that HIV can not be transmitted, even if you don’t use condoms.
Please see more here at U=U.
It’s great that you’re CD4 count is normal and HIV is undetectable. Please ask the clinic what 0.200ML means. It looks like it’s the volume of the test.
My results for the past 3years they have been lower than dectetable does mean I’m undectetable and that i can have sex without condoms and I will not trasmitt the virus.
My CD4,count is at 728
Viral load is lower than dectetable
Then there’s something like 0.200ML
What does this mean
Hi Jabulile,
It means that your HIV is under control. You’re doing really well. It also means that if you were to have sex without a condom that you can’t transmit HIV.
Yesterday I go for checkup my results were written as viral load is lower than dectetable *OK* what does that mean
Hi Nonhlanhla,
What has your viral load gone up to?
Hi am nonhlanhla am hiv positive and pregnant why is my viral load is going up while the last time I check it was 115 and i drink my pills same time everyday and my 8month’s pregnant
