ssDNA ANTIBODY, IgG

Mnemonic

DNA SS

Guidelines

The ssDNA antibody test detects ssDNA and some dsDNA antibodies. As a result, patient samples should also be tested for dsDNA antibodies in order to more accurately determine the level of anti-ssDNA antibodies. By calculating the ratio (ssDNA/dsDNA), a conclusion can be made as to the presence of ssDNA antibodies. A ratio less than or equal to 1.0 indicates the absence of ssDNA antibodies. A ratio greater than 1.0 indicates the presence of ssDNA antibodies.
