Symptom narrative

Cold Agglutinin Disease. 11/2021, First symptom was feinting after going outside for 30 min, to work in 30degree temps. Trip to ER found no reason although my CBC was out of range on many results. No Cold Agglutinin test was performed. Various cold hives occurred without reporting or knowing why. Jan 2023 my blood donation to agency was rejected as it was Hemolized. Jan 2024 went to my Primary Dr, who referred me to a Hematologist as my blood was still out of range. Dr ran multiple blood tests and Feb 2024 I received my first Titer score of 1024. Diagnosed with Cold Agglutinin Disease. All know causes were tested for and I was negative for them.
