This isn't a pregnancy test -- an elevated reading is only one of many factors that may lead to a diagnosis and treatment decision. Best wishes. ...Read more

Since my liver biopsy showed fatty liver, why is my actin antibody 62 then 54?

Since my liver biopsy showed fatty liver, why is my actin antibody 62 then 54?

Just an association: Assuming your actin antibody is actually a f-actin smooth muscle antibody (asma or sma) this is checked in patients as a chronic liver disease workup. There is an overlap and association with the asma and fatty liver disease seen in up to 20% of those with fatty liver disease. You might even have a positive ANA also. Nothing to be worried about. You can ignore it (if you only have fatty liver)! ...Read more

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. ...Read more
