That's not a very high antibody titer (or level), Frankie, which is a good thing.

A positive ANA test using a HEp-2 substrate means the lab used human cells to detect antinuclear antibodies in the blood — it's actually the most common and sensitive method used for this test. Here's a breakdown of the results:
- Positive result — Antinuclear antibodies were found in the blood
- Titer of 1:320 — This is Show Full Answer
A positive ANA test using a HEp-2 substrate means the lab used human cells to detect antinuclear antibodies in the blood — it's actually the most common and sensitive method used for this test. Here's a breakdown of the results:
- Positive result — Antinuclear antibodies were found in the blood
- Titer of 1:320 — This is considered a high titer, meaning a significant level of antibodies was detected. A result of 1:80 or above is generally considered positive, so 1:320 is notably elevated
- Homogeneous pattern — This means the antibodies are spread evenly across the cell nucleus under the microscope, and is one of the patterns most commonly associated with lupus It's important to know that a positive ANA alone doesn't confirm a lupus diagnosis. Around 15% of healthy people can also test positive. Doctors use the ANA result alongside symptoms and additional tests — like anti-double-stranded DNA — to build the full picture.
Sharing these specific results with a rheumatologist is really the best next step, as they can interpret them alongside personal health history and symptoms.

Very few people with PMR get TA--I've read about 10-20%. Just watch for headaches in the temple or vision changes.

Good. That was the last bloodwork result I got in. One question. If this is actually PMR how concerning is Giant Cell Arteritis?
