Hello and thank you for posting your query on HCM
Rouleaux formation is not a disese per se.
It is seen in large number of disease both malignant and non-malignant.
Since you are suffering from a chronic disease fibromyalgia
, it could be due to that.
In addition to rouleaux formation, I would like to know your hemoglobin
levels ane also ESR
in case you have got these tests done.
Other tests which you can get done are Direct and Indirect Coomba test.
The combination of these tests can give abetter idea than a single test.
I hope you get back to me with all the relevant details
