What does it mean when a lab test for strep pneumoniae IgG 23 serotypes comes back as all 23 serotypes being low?

What does it mean when a lab test for strep pneumoniae IgG 23 serotypes comes back as all 23 serotypes being low?

Further evaluation: If you have been vaccinated or have a history of recurrent sinus or respiratory infections, this response is unusual. I would consider an immune evaluation to make sure there is no other reason for this response (ie antibody or other immunodeficiency). I would also consider a Pneumovax vaccination to help boost your immune response if you are having recurrent infections. Discuss with your doc. ...Read more

Please explain S.Pneumoniae IGG serotypes and what a low count signifies in a middle aged adult. Also explain the Strep.Pneumo vaccine and its results?

Subclasses: Serotypes actually represent the different strains of S pneumococci with 23 of them being most common in causing human diseases. If you have not received any vaccination or had any infection, low antibody titers are not necessarily abnormal. The best way is to get immunized then check the titers again. Pneumococcal vaccine is intended to reduce the risk of systemic invasion by this germ. ...Read more

Very low in all 23 s. Pnuemoniae IgG serotypes as well as igg1, 2, 4. What could this mean?

Very low in all 23  s. Pnuemoniae IgG serotypes as well as igg1, 2, 4.  What could this mean?

Depends: So all of this depends on a few things: in regards to the s. Pneumo. Serotypes, have you been vaccinated with a pneumococcal vaccine recently? If not, that may be your next step and then repeating the bloodwork in 4-6 weeks to assess the response. The most important thing is the total igg level (igg1 + 2 + 3 + 4). If that is within normal limits, then it is reassuring. Consult an allergist. ...Read more

Can someone interprete what this means? In regards to strep.Pneumo. Igg ab(14 sero)...Type 3= .01 ug/ml, type 4=0.2, type 9v, 12f and 23f all = 0.5

See below: These are nonprotective titers to s. Pneumo--this means that your "immunity" to this organism has waned over time. This can often be a normal finding in a 42 year old. To determine whether or not your immune system is working well, most immunologists would administer a Pneumovax vaccine and re-check the titers in 6 weeks. The titers should increase if your immune system is normal. ...Read more

What does the "mycoplasma pneumoniae IgG IgM ab" test for?

What does the "mycoplasma pneumoniae IgG IgM ab" test for?

See below: A positive mycoplasma igm antibody would indicate a recent infection with this organism. If the igm antibody is negative and the mycoplasma igg antibody is positive this would indicate a past infection with mycoplasma. ...Read more

What does it mean that my mycoplasma pneumoniae IgG came back very high?

What does it mean that my mycoplasma pneumoniae IgG came back very high?

Probably nothing: Ig the igm fracture is negative you do not have active disease. The igg likely indicates past and not present infection. ...Read more

My ch50 is 394 and normal range upper limit is 300. C3 and C4 are normal. Can you tell me what this means? My IgG subclass 2 serotypes are all low

My ch50 is 394 and normal range upper limit is 300.  C3 and C4 are normal.  Can you tell me what this means?  My IgG subclass 2 serotypes are all low

Ignore it: Ch50 is hard to do correctly, unless the value is way off i would ignore it, and it may just be up from a transient infection or be your normal. Unless your igg subclass is very low, i would ignore this as well. We pathologists say, "focus on the person, not the numbers." by the way, i attended lfhs and perhaps we know one another. ...Read more
