Posted on Fri, 11 Jul 2014
Question: Hey Doctor,

I tested for all STD and only chlamydia came out. And it shows chlamydia igg 1.3, what does that mean? It has nothing else but IgG 1.3. As i was reading around IgM have to show before im known as positive in chlamydia.

I have not contracted Chlamydia which was the last checkup nor went into any treatment before. But had unprotected oral sex it was only with one partner that i had unprotected oral sex. Sex is all the while protected.

Please advise.

Brief Answer:
chlamydia IgG 1.3 shows a good immunity

Detailed Answer:
Hello,

Welcome and thanks for posting your query to the forum.

I can understand your concern for the report showing chlamydia IgG 1.3.

After reading your query and interpreting with the reports let me first reassure you that you are not suffering form chlamydia infection. The report is just showing either a good immunity towards chlamydia or late infection towards which you have got good immunity now.

To explain you elaborately - whenever we are exposed to any infection like chlamydia or any other then it is not possible that it will be clinically manifested. Clinically the disease is manifested in terms of signs and symptoms only where the immunity of the body is not able to contain or fight back the infection.

Even then the body produces antibodies against that infection. The first antibody produced is IgM which shows that the infection is currently going on. Later on IgG is produced as a part of good immunity or as sign of late infection in past.

In your test values you can see that it is IgG which is positive and not the IgM. IgM is the antibody which is expressed when there is an active or a recent infection is present. As soon as immunity towards that particular infection is acquired such as in your case towards chlamydia, then IgG is expressed. IgG positivity means either a good immunity or a very late infection in past which may or may not have had been expressed.

Your IgG is well above the cut off value meaning a very good antibody level for protection.

So for the chlamydia part you should not be worried at all.

The IgG is conclusive evidence of your clear status. You do not require any further testing and just relax.

Hope the informations will relax you. I will be happy to help for any further queries.

Wish you good health,

Thanks Doctor for the reply. Very thorough explanation.

Now my follow up question you mention either i have gotten it in the past and have cured or have strong antibody.

So my question now is, if i did not have gotten in the past and cured. Meaning to say that my current partner have chlamydia?

Brief Answer:
No chlamydia from current partner

Detailed Answer:
Hello young fellow,


Welcome again to the forum and thanks for further follow up.

Now regarding your further query- we can not predict from the IgG report that when had you got infected from chlamydia. We can not detect or estimate the exact time since you got infected. Therefore we can not predict whether it is from your current partner or from any other person in past.

But as per my clinical experience i can reassure you that it is not from your current partner. It is because if the fact that had it been from your current partner then there would had been recurrent infection and so IgM would also had been positive, which is actually not.


So relax for any possibility of chlamydia and do not give any second thoughts about it.

Always use protection and follow safe sex practice.

My all best wishes for your good health.

I hope these informations will relax your mind. I will be glad to answer any further queries or if not then can close the discussion and rate the answer.

With regards,

Dr Sanjay Kanodia
