I am always trying research my ANA pattern and figure out what these are markers for and what it all means to me.
I am high-titer nucleolar ANA and positive THTO antibody. I can find information on nucleolar ANA but nothing on THTO antibodies.
Anyone have these and does anyone know where to find more information?

I'm not sure what the THTO stands for, but here is a link for Auto-Antibody Patterns.

hope this helps

Hi Jen ,

Here's a site I go to for 'funky' blood work.


"Utilities: The Th/To Ab is present in 10-19% of patients with Diffuse Cutaneous Systemic Scleroderma (SSc) and in 3% of patients with primary Raynaud's Disease. It has been shown to be highly specific for patients with SSc. ""

Have a good day, Everyone.

Celia and Margaret have provided a couple of great links, both of which are found on our antibodies page.

Hi Jen,
I too have a pos ANA (1:640) w/nucleolar pattern. I didn't have the test for THTO, but here is a list of the tests I gave 8 vials of blood for yesterday:

C3 C4
Anticentromere Antibodies
Anti SCL70
Lupus Anticoagulant/anticardiolipin

Whew! When I got up to leave, the lab tech said she would be keep me in her thoughts.
Do these look familiar to everyone?
I'm guessing, from my reasearch, that the Anti SCL70 is the big red flag my rheumatologist will be looking for. The others look like she is checking for Lupus.

Good luck to you! :)
ANA+, Nucleolar pattern, anemia.

Hello and welcome!

I am negative for slc70. I am not sure that if one is positive that it is a red flag...but you can be without it and have scleroderma.

I was so whacked out when I had tests trying to figure out what was going on (mine sent me to a 3 week stay in the hospital) that I don't really know what all was tested for. I know I was tested for Parvo.

Take care,
