Is an antinuclear antibody blood test result of 1.32 low, medium, or high?  Is it something to worry about?

If 1:320, high-ish: Anas are reported as a ratio of how dilute the serum is when the antibody is still detectable, and the lowest ratio reported is usually 1 to 40, written 1:40. Meaning if you dilute the serum 40 fold, you can still find antibody. The next reading is 1:80, then 1:160, then 1:320. The number you write looks like it could be 1:320. That's a significant amount and might cause symptoms. Make appt w doc. ...Read more

?: I do not understand the digestive part of your question and the ANA is not measured as a titer of 1:100. That said, a positive ANA and protein in the urine could be indicative of lupus or related diseases. Please consult with a rheumatologist or nephrologist (kidney specialist). ...Read more
