Ask Your Health Question and Get an Answer ASAP
What issue are you dealing with? i.e. why was the testing done?
Please post the reference range for your lab for the results you had. Reference ranges will vary from lab to lab depending on the equipment they use.
By "NA" do you mean antinucleaer antibodies (ANA)?
It's unusual to run these tests unless someone is having symptoms.
I've included the protocol for connective tissue disorder testing. In general, an ANA greater than 3.0 and an RNP antibody test greater than 1.0 would indicate a mexed connective tissue disease. This protocol is designed to diagnose scleroderma vs lupus vs mixed connective tissue disorder vs Sjogren syndrome vs polymyositis.
Here is Mayo's discussion of mixed connective tissue disease (MCTD):
MCTD can be very mild so that there are few, if any, symptoms. Your provider who ordered the test will need to discuss the test results along with your clinical presentation with you. There are many treatments for this.
