What is a titer?

What is a titer?

Dilution/concentrati: The term titer is usually used when the lab serially dilutes a specimen and tests for the presence of a substance, usually antibody. The highest dilution giving a positive results is called the tiler, e.G, if antibody is detectable at a dilution of 1:64, the specimen is said to have a titer of 64. ...Read more

I had a Herpes-6 IgG test done and normal is less than 1:80 titer but my result was exactly 1:80 titer. Significance? I was 15 when the test was done.

Do not worry: Almost everybody gets infected with herpes 6 and if otherwise healthy we are none the worse for it. Since your test was done three years ago and you are writing about it, you are fine and will not see any ill effects from the lab result. ...Read more

Does hep b titer tell if you were previously infected? Vaccinated as child. Result showed 11miu/ml. 10miu is min. Is mine low & should I be concerned?

Does hep b titer tell if you were previously infected? Vaccinated as child. Result showed 11miu/ml. 10miu is min. Is mine low & should I be concerned?

Probably not: If you were vaccinated as a child and still have detectable antibodies left from that vaccine, chances are good that your vaccine ( it should have been a series of three doses) has protected you all this time and is still protecting you. More tests would be required to try to learn if you were ever infected, or are currently infected. The titer only says you have made a response to vaccine or bug. ...Read more

Is it safe to dismiss a positive ANA speckled with a titer of 1:640 if CBC ok. Lupus panel negative. Metabolic ok. Urine ok. Serum protein ok?

Is it safe to dismiss a positive ANA speckled with a titer of 1:640 if CBC ok. Lupus panel negative. Metabolic ok. Urine ok. Serum protein ok?

Yes and no: We have a saying in pathology / lab medicine, "treat the person, not the labs." plenty of healthy folks have medium-titer speckled ana's. The real question is, "do we want to treat you for lupus or whatever, with all the unpleasantness that this involves?" i think the answer is "no" based on what you're shared if your physician agrees. Remember the ANA should new symptoms develop. Good question. ...Read more

Since my ANA titer of 1:320 came back my knee has been swollen and leg now my back hurts when i breathe in and out do I have a immune disease ?

Since my ANA titer of 1:320 came back my knee has been swollen  and  leg now my back hurts when i breathe in and out do I have a immune disease ?

Only a screening: An "ana" is a blood test used to screen a person for the possibility of several autoimmune diseases. It is important to remember that this is a screening test and a positive result only indicates more testing may be warranted. No blood test is perfect, and getting to a diagnosis is usually much more complex than drawing blood and looking at a number on the results report. ...Read more

What does it mean when your fana is abn positive?  Fana titer is 1:160 . Fana pattern is speckled.?

ANA?: We have antibodies in our blood that repel invaders such as virus and bacteria. Antinuclear antibodies (anas) are unusual antibodies that bind to structures within the nucleus of cells. The nucleus contains the dna, the primary genetic material. Anas are found in patients with autoimmune diseases. Interpreting a value and pattern without the remainder of history and physical is not feasible. ...Read more
