This comes on by having a wheezing episode and then I begin coughing
. This brings on the process of coughing up
blood. It may happen several days in a row or may be months in between. The blood is bright red and may contain some mucus in it. The blood sample is about a quarter size and may happen 3 to 6 times in a row. I have had a lung spirometer test, sputum sample, a bronscopy, lung biopsy, multiple CAT scans, multiple chest x-rays, a PET scan and many many blood tests.
