what does an ana titer of 1:160 mean

They were 1.40. One multicenter study reported that 31.7% of normal individuals were ANA positive at 1:40 dilution, which was decreased to 13.3% at 1:80 and 5.0% at 1:160 dilution. ANA Titer .

ANA 1:40 is found in 20 – 30% of healthy people. So let’s take an example.  Your doctor runs an ANA and it comes back as 1:320 speckled pattern.  So what does that mean?  When the lab tech was looking at the fluoresceinated antibodies, it basically literally looked speckled.  There are many other kinds of patterns: homogenous, centromere, nucleolar, speckled, rim etc.  Each of these patterns possibly indicate the presence of specific nuclear antibodies.  For example, the presence of a speckled positive ANA indicates the presence of these specific autoantibodies, SSA, SSB, RNP, Smith, and Ku antibodies. 5% of the SLE cases show persistently negative results. Thus a titer of 1:640 shows a greater concentration of ANA than 1:320 or 1:160, since it took 640 dilutions of the plasma before ANA was no longer detected. A titer above 1:160 is a positive test result. That’s why having unexplained inflammation, a butterfly-shaped rash across the face, a low-grade fever, and other feelings of generally feeling unwell should be checked on if they continue in a prolonged fashion. All healthy individuals who became ANA negative had an ANA titer of 1:80 at baseline.

A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled. A positive test for ANA does not mean you have an autoimmune disease. 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.

Unfortunately, the tech cannot count how many ANAs they see.  Instead, they see how much they can dilute the blood and still see the fluoresceinated antibodies.  So when you see and ANA of 1:80, that means the tech really wasn’t able to dilute very much.  This is a low level.  If you see a value of 1:640, that means they were able to dilute a lot more.  This is a higher level.

The normal titer of antinuclear antibody is 1:40; higher titers of this autoantibody can indicate that a person is affected by an autoimmune diseases. Some of the conditions that can cause a high ANA titer include Lupus, scleroderma, and rheumatoid arthritis (WebMD).

The combination of low titers of antibody (<1:80) and no or few signs or symptoms of disease portends a much smaller likelihood of an autoimmune disease. The level to which a patient's sample can be diluted and still produce recognizable staining is known as the ANA "titer." The test finds small amounts of these antibodies in up to 15% of healthy people. Certain autoimmune diseases, however, can still be present with a negative test result. Reference ranges indicate the minimum titer ratio that is considered a positive result on this test.
