Anyone can help?

I will respond in a moment.

Typing my answer.

Thank you for your patience.

What are tests for...


  1. ANA
  2. Anti-Ds DNA
  3. Anti-Sm antigen

These are the main types of antibodies that are tested with a blood test.

POTS (postural orthostatic tachycardia syndrome)

The main test for this is what is called as a tilt table test. You can google this test to see how it is done.

CIDP (chronic inflammatory demyelinating polyneuropathy)

This is mainly a clinical diagnosis but there is test called as nerve conduction study that will also aid in the diagnosis of this condition.

This session is open for any further questions that you may have.

Is the Lupus blood test normal blood test or specific for Lupus?

The ANA (antinuclear antibody) test is not specific for lupus but is still a screening test for it. This means that a positive test would not mean much and would need further investigations but a negative test would pretty much rule out lupus.

The other blood tests for lupus that I mentioned are very specific for lupus, which means if they are positive, you will almost certainly be having lupus.

You said for CIDP (chronic inflammatory demyelinating polyneuropathy), it is a clinical diagnosis, what does that mean?

Clinical diagnosis means that this is diagnosed by history and physical examination mainly and aided by nerve conduction studies as well to some extent.
