I know my ANA test came back positive, but today my GP gave me the numbers. 1:320.  He said they were high but did not elaborate too much.  I have a Rhuematologist appt. next week but am wondering if these are considered high or borderline high. 
Thank you

Hi Dazed, One suggestion I might make is to tell them you want copies of all your records.

As for your ANA a normal person's ANA is 1:40 to 1:80 anything over 1:80 is considered possitive. My ANA as been 1:2560 it's 1:1280 right now. You will find out however that your ANA really doesn't mean alot. Some people with A/I don't even have a possitive ANA and some healthy people do have a possitive ANA. That's why this diseasse is so frustrating. It's hard to figure out.

see clear as mud!

It's been kind of quiet on the forum the last few days and since you've only received one reply I thought I'd try to step in and help a little bit until a few of the regulars pop in and can answer your questions.

I went to the Lupus Foundation's web site and found information on the ANA test that you can read.  I tried posting the link but for some reason it keeps saying the link is bad so I'm just going to go ahead and paste the info about the test.  I hope this helps.

The Antinuclear Antibody (ANA or FANA) Test

Positive ANA
The immunofluorescent antinuclear antibody (ANA or FANA) test is positive in almost all individuals with systemic lupus (97 percent), and is the most sensitive diagnostic test currently available for confirming the diagnosis of systemic lupus when accompanied by typical clinical findings. When three or more typical clinical features are present, such as skin, joint, kidney, pleural, pericardial, hematological, or central nervous system findings as described above, a positive ANA test confirms the diagnosis of systemic lupus.

Weakly positive ANA
The test can even be weakly positive in about 20 percent of healthy individuals. While a few of these healthy people may eventually develop lupus symptoms, the majority will never develop any signs of lupus or related conditions. The chances of a person having a positive ANA test increases as he or she ages.

Negative ANA
A negative ANA test is strong evidence against lupus as the cause of a person's illness, although there are very infrequent instances where SLE is present without detectable antinuclear antibodies. ANA-negative lupus can be found in people who have anti-Ro (SSA) or antiphospholipid antibodies.

ANA Titers and Patterns
ANA laboratory reports include a titer (pronounced TY-tur) and a pattern.

  • The titer indicates how many times the lab technician had to dilute plasma from the blood to get a sample free of the antinuclear antibodies.
    • For example, a titer of 1:640 shows a greater concentration of anti-nuclear antibodies than a titer of 1:320 or 1:160.
  • The apparent great difference between various titers can be misleading.
    • Since each dilution involves doubling the amount of test fluid, it is not surprising that titer numbers increase rather rapidly.
    • In actuality, the difference between a 1:160 titer and a 1:320 titer is only a single dilution. This does not necessarily represent a major difference in disease activity.
    • ANA titers go up and down during the course of the disease, and a high or low titer does not necessarily mean the disease is more or less active.
    • Therefore, it is not always possible to determine the activity of the disease from the ANA titer.
    • A titer above 1:80 is usually considered positive.
    • Some laboratories may interpret different titer levels as positive, so one cannot compare titers from different laboratories.

  • The pattern of the ANA test can sometimes be helpful in determining which autoimmune disease is present and which treatment program is appropriate.
    • The homogeneous, or smooth pattern is found in a variety of connective tissue diseases, as well as in people taking particular drugs, such as certain antiarrhythmics, anticonvulsants or antihypertensives.
    • This homogenous pattern is also the one most commonly seen in healthy individuals who have positive ANA tests.
    • The speckled pattern is found in SLE and other connective tissue diseases
    • The peripheral, or rim pattern is found almost exclusively in SLE.
    • The nucleolar pattern, with a few large spots, is found primarily in people who have scleroderma.

Because the ANA is positive in so many conditions, the results of the ANA test have to be interpreted in light of the person's medical history, as well as his or her clinical symptoms. Thus, a positive ANA alone is never enough to diagnose lupus. On the other hand, a negative ANA argues against lupus but does not rule out the disease completely.

A Positive ANA Does Not Equate to Having a Disease
The ANA should be looked at as a screening test. If it is positive in a person who is not feeling well and who has other symptoms or signs of lupus, the physician will probably want to conduct further tests for lupus.

If the ANA is positive in a person who is feeling well and in whom there are no other signs of lupus, it can be ignored. If there is any doubt, a consultation with a rheumatologist should clarify the situation.

Thanks so much for the info. It was very helpful. I am seeing a Rheumatologist for the first time this week and will fill you in on the outcome.

Have a great week.

  I hope your appt goes well. My ANA stays at 1:640 most of the time. Please keep us updated and take care. You will be in my thoughts and prayers.
