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?

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

No antibodies: If you have not received the pneumococcal vaccine then you have probably not been infected with any of these strains of pneumococcus, a gram positive bacteria that causes pneumonia, sinus & ear infections & meningitis. If you have received the vaccine & these values represent antibody levels obtained 4-6 weeks later then you have hypogammaglobulinemia. Probably cvid. See your immunologist. ...Read more

What are the standard ranges/values for a pneumococcus pneumoniae antibody igg levels? ug/mL Mine range from 0.3 - 3.3. No standard range is listed.

What are the standard ranges/values for a pneumococcus pneumoniae antibody igg levels? ug/mL  Mine range from 0.3 - 3.3. No standard range is listed.

>1.3: Usually 1.3 or above would be considered protective level for IgG. More importantly, it is the % of the total response to the number of strains tested which is more meaningful. As a post-vaccination response to Pneumovax 23, the % of protective level cover 70% or more to be considered normal. ...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

7yo daughter has Eos 3700, IgG 580, CD20 (Pan B) 932.  She was tested because she is having recurrent strep.  Does these results point to cancer? 

7yo daughter has Eos 3700, IgG 580, CD20 (Pan B) 932.  She was tested because she is having recurrent strep.  Does these results point to cancer? 

Unlikely but: She does have elevated eosinophil count which needs be repeated. If the elevation is persistent, you need to bring her to an allergist or hematologist for an evaluation. Although hypereosinophilia can be from a form of "cancer" , I think the likelihood is quite low. By the way , these are not tests intended for recurrent strep infection. Need to check close contacts including your pets. ...Read more

2 months ago i had ^ IgM results for h.Pylori, Lyme & HSV + strep b. Now after taking doxy & amox i still have strep, ^ IgM but no igg. Any ideas?

IgG: Elevated igm represents a recent or current infection. Igg provides long-term protection after exposure to an infectious agent. It is unusual to have no igg present and thus you need to consult an allergist/immunologist to find out if you have an impaired immune status. ...Read more

What is the best way to clean germs such as strep pneumoniae off of objects and what cleaning product should be used?

What is the best way to clean germs such as strep pneumoniae off of objects and what cleaning product should be used?

In normal daily life: In normal daily life, we don't think about cleaning the home or office of Strep pneumoniae germs, because they are considered mild (not extremely deadly, not like anthrax), are more likely caught by direct human contact or breathing in some sick person's sneeze or cough, and we get immunity to many strains of it (by prior illnesses or the VACCINE). Any typical home cleaning product are fine. Any. ...Read more

Strep pneumoniae from sinuses in blood, told i got it recently. But could sinuses have been infected for longer leading up to it?

Strep pneumoniae from sinuses in blood, told i got it recently. But could sinuses have been infected for longer leading up to it?

Yes most likely: if the bacteria found a way into your bloodstream (bacteremia), then you have had sinus infection for a while -- typically an acute infection would not occur in that way. Your immune system works overtime to prevent bacteria from entering your bloodstream, unless it has been overwhelmed by the infection. And that usually occurs over a period of weeks, not days. Thanks for trusting in HealthTap. ...Read more

If you had a germ such as strep pneumoniae on your skin, then had a blood test, would that introduce germ into blood causing infection?

If you had a germ such as strep pneumoniae on your skin, then had a blood test, would that introduce germ into blood causing infection?

No risk, no worry: Skin bacteria almost never get into the bloodstream from having blood drawn. Also S. pneumoniae is not likely to be present on the skin in sigificant numbers. Nothing to worry about. ...Read more

What is most likely way strep pneumoniae gets into bloodstream? I know it's rare but wonder- can u get this germ from a sneeze? Doorknob? Kissing?

What is most likely way strep pneumoniae gets into bloodstream? I know it's rare but wonder- can u get this germ from a sneeze? Doorknob? Kissing?

Uncommon: This bacteria is present in our air and surroundings but it does not cause infection all that easily. The most common first site of infection would be a Pneumonia from breathing in his germ, which is rare in young people(older folks get it more often). From lungs it can get into blood steam. So this latter phase is even rarer and only happens when patient is not treated with antibiotics promptly. ...Read more

Had strep. pneumoniae blood infection, treated. Got imported down feather pillows at same time. Is possible feathers transmitted germ/illness to me?

Had strep. pneumoniae blood infection, treated. Got imported down feather pillows at same time. Is possible feathers transmitted germ/illness to me?

No association: Strep pneumoniae is a normal bacteria in the environment and carried by healthy people. It isn't caught from pillows, clothing, food, etc. You either were carrying it before you got sick or picked it up from almost anyone you have been around. For sure not from your imported pillows. Hope you've recovered well. Best wishes. ...Read more

Strep pneumoniae found in blood, had meningitis.Told from sinuses, but lots of blood tests year before.Possible germs from needles/tests caused it?

Strep pneumoniae found in blood, had meningitis.Told from sinuses, but lots of blood tests year before.Possible germs from needles/tests caused it?

No: There is no way a contaminated needle gave you a germ that sat around for a year and then decided to infect you. Once it finds a way in, strep pneumonia will multiply fast enough to make you sick within 24 hrs.The germ is actually carried in the nasal airway at various times in normal people who never get sick from it. ...Read more
