Not diagnostic: In general, lab tests are used to support a clinical diagnosis and thus a positive test per se does not provide a diagnosis without abnormal physical findings or symptoms. On many occasions, an abnormal lab test is not associated with any disease condition especially when the value is only slightly abnormal. If you do hundreds of tests on a healthy person, you will likely find something abnormal.

Antibody (Definition)

An antibody is a protein the body's immune system makes to identify potentially harmful substances in the body. Antibodies attach to the substance on a molecular level and mark it so the immune ...Read more

What does low pneumococcal antibodies mean? Blood showed good immune system except that? Can it cause chronic sinusitis and bronchitis?

What does low pneumococcal antibodies mean? Blood showed good immune system except that? Can it cause chronic sinusitis and bronchitis?

Yes: I assume this is a antibody level measured after the pneumococcal vaccine. If so, it means your immune system is not responding to the bacterial proteins in the normal way. Patients who mount a weak response to bacterial infections may be at higher risk for recurrent respiratory tract infections such as sinusitis and bronchitis.

What does the result of 'Low Positive' for an NMDA Receptor Antibody test mean?

What does the result of 'Low Positive' for an NMDA Receptor Antibody test mean?

Depends: Why was the test ordered? I would contact the Dr who ordered the test to explain the results to you. They know the clinical context. Low Positive can also mean not exactly positive or not clinically significant.

Dr. Tested my pneumococcal antibodies- they were low she gave me pneumo vac retest in 5 weeks, if it comes back low again. What does this mean?

CVID: Aka combined variable immunodeficiency. This test is done because you have recurrent sinusitis, bronchitis or pneumonia & screening tests for weak immune system - CBC & diff, quantitative immunoglobulins, ch50- are ok. A 2nd low test means you don't make adequate antibodies against some bacteria that infect the respiratory tract. Antibiotics & gamma globulin injections will help you.

Blood donation refused due to low antibodies. What does that even mean? Should I be worried?

Blood donation refused due to low antibodies. What does that even mean? Should I be worried?

Not sufficient info: Screening for blood donation usually does not include measuring general antibody levels. The blood bank that tested your blood should be able to provide an explanation.

The doctor said my pneumococcal antibodies antibodies are low. What does that mean?

The doctor said my pneumococcal antibodies antibodies are low. What does that mean?

Measures immunity: It is common for physicians who assess persons with recurrent infections for immune deficiency to check pneumococcal antibody levels. A person with a well functioning immune system should be able to produce specific antibody levels to bacteria (especially if they have received the vaccination). If levels are low, in context of recurrent bacterial infections, further evaluation of immunity needed.

In my labs it shows a positive ANA and then the lab automatically checks for antibodies...The only one was a low positive rnp. What does that mean?

In my labs it shows a positive ANA and then the lab automatically checks for antibodies...The only one was a low positive rnp. What does that mean?

Not a great deal.: Positive anas can be "false" positive. On the other hand an rnp antibody is not false. This combination would indicate mixed connective tissue disease. That having been said, I have many patients with a low titer rnp positivity and no signs of disease. Mctd is rarely a disease with major serious issues as other dx.

Got my test results online. Says ANA speckled is at 1250. And other antibodies are found like ssa, ssb, rnp, smith, but are low levels. This mean SLE?

Got my test results online. Says ANA speckled is at 1250. And other antibodies are found like ssa, ssb, rnp, smith, but are low levels. This mean SLE?

Not necesarily: While these tests point to a probability of a collagen vascular disease, this could be lupus, mixed connective tissue disease, etc. The doctor ordering these tests knows your history and physical examination findings and should be the one interpreting these tests. Should be a Rheumatologist.

Possible spider bite culture came back g strep fluid drained have low temp antibiotics. 24 hrs later arm red/swollen hot what is meant by g strep?

Possible spider bite culture came back g strep fluid drained have low temp antibiotics. 24 hrs later arm red/swollen hot what is meant by g strep?

Serious: It is possible that the spider bite could be secondary infected by group g strep. Also it could be a primary infection. The condition you are describing is most likely cellulitis caused by group g strep. Please, see you doctor as soon as possible so the appropriate treatment can be started.

I had low soreness on one testicles. Dr prescribed antibiotic. Soreness has gone away. Did this mean I had an infection? Would that affect fertility?

I had low soreness on one testicles. Dr prescribed antibiotic. Soreness has gone away. Did this mean I had an infection? Would that affect fertility?

Possible. No.: You may have had an infection that the antibiotics cured. Then again you might not have had one and the pain went away on its own. I t is unlikely that this will affect fertility.

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

Probable hypothyroid: The free t4, not free T3 (liothyronine) test, is necessary here. Positive antibodies indicate hashimoto's thyroiditis, the most common cause of hypothyroidism. It may just be early in the process to cause the TSH to be elevated.

Tests show I have a normal tsh, T3 (liothyronine) but low T4 & free T4 and antibody of. 7 what do these results mean?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. It would help to know the actual values of all the hormones.

Hepatocellular disease, seizures, low blood count, anticardiolipin antibodies, arthritis, rash on hands and numbness in legs. What does this all mean?

Auto-immune disorder: You have described features of auto-immune disorder. For example, a person with lupus could have all these features. You need evaluation and treatment by a physician in consultation with specialists in more than one field.

What does increse in antibodies mean?

A warrior increase: Think of an antibody as a soldier to help you beat the enemy (infection) if you have increasing antibodies you have more warriors. The problem here is if the warriors decide to fight against your own body rather than infection. You then have an auto-immune disease like rheumatoid arthritis.

What could cause a low number of antibodies?

Meds or diseases: There are many reasons. Immune suppressant medications (e.g. steroids, azathioprine, mycophenolate), chemotherapy, certain seizure meds can all cause low antibody levels. Also, immune deficiencies like CVID lead to low levels. Certain infections like HIV can cause it, too. Excessive loss of protein from chronic diarrhea can cause it. Talk with an immunologist if you have more questions.
