After further research on the symptoms of last month's collapse and their possible causes, I had a suspicion that the culprit was the filet mignon. Regular food poisoning should have left some traces of the causative organism - none were found after testing blood, urine, etc. The restaurant is a high class operation, I did not want to besmirch its reputation. So when the one month recheck with the primary care doctor drew near, at the blood draw the week before, I asked the nurse if another test could be added to rule out a possible cause for the collapse. She checked with the doctor who agreed to add the $50 test to the order. A week later after the usual preliminaries, the nurse appeared with the test result and was delighted to announce that my husband is positive for alpha galactose syndrome: he is now allergic to beef, pork and lamb. The primary doctor came in and wanted to know who had asked for the alpha gal test? I raised my hand. He then proceeded to thank me, alpha gal had not been on his radar even tho he knew I have alpha gal. It was a reminder to him, as his practice is now primarily rural. In my neighborhood the deer carry the lone star ticks from cow pastures to mini-farms with sheep, goats, hogs and horses. Chickens run loose all over the place.
Now we know how to avoid a repetition of that horrible night that led to 3 days in ICU. But it raises a new question: How will alpha gal affect the lifespan of my husband's bovine aortic valve replacement that he had almost 6 years ago? The doctors will have to avoid using heparin on him. What little data there is indicates heparin usage causes a fierce reaction.
