Does ELISA test for ANA titre result come out in iu/ml? what's the reference value in iu/ml? Why some results show a ratio like 1:40? any difference?

In brief: Different tests and

units. A result of 1:40 denotes that the test was done at a 1:40 dilution of serum. For ANA, that is the starting dilution and if the test is negative at that dilution it is considered negative.
