An example of these patterns is illustrated in Figure 2 over the page. Further elucidation of the specificity of the antibody is done by ENA and dsDNA testing. These are useful in confirming the significance of a positive ANA and will help to lead to a diagnosis of the type of autoimmune disease. Extractable Nuclear Antigens (ENAs) Detecting antibodies to ENAs involves testing patientâs serum for antibodies against various specific components of the cell nucleus.

All you need to do is place the container with liquid into a microwave and heat it for about 10 seconds. You can use a temperature strip to test if the sample is usable. Leaving the urine in for a longer period will give it an unusually high temperature and this is where it gets tricky. You can wait for the sample to cool down a little, but know that synthetic urine can be destroyed by too much heat.
