The following tests are used to exclude Hughes Syndrome (and variants) as
being the cause of CFS. All tests must
be negative (there are many variants of Hughes Syndrome).
Immune System Activation of Coagulation Panel
For detection of "sticky blood" there are several tests. The usual US-CFS
test is the ISAC Panel from Hemex laboratories (http://www.hemex.com)
Anticardiolipin Antibodies
This is a cheap test, but it requires two positive tests 6 months apart
for a positive result. .
It is suggested as a possible pre-ISAC panel test to justify the ISAC expense.
(Note: a negative results does not imply a negative ISAC panel)
Lupus Anticoagulant
The name does not imply Lupus -- rather an antibody that is also seen
with Lupus. Moderate number of positive results.
Wasserman Reaction
This is a very old syphilis test, a positive test does not imply syphilis,
rather one form of Hughes Syndrome. Least amount of positive results.
