Blood presure medications help keep the blood vessels open and then decrease the symptoms of raynauds. ...Read more

I've had a blood test called cold agglutinins. Doctor is querying raynauds. What else could the doctor be looking for when asking for this test?

I've had a blood test called cold agglutinins.   Doctor is querying raynauds. What else could the doctor be looking for when asking for this test?

Several: Glad you asked. Cold agglutinins damage red cells in the cold and may be elevated for unknown reasons in mycoplasma pneumonia, and also define the uncommon cold agglutinin hemolytic anemias. Cryoglobulins are antibodies that precipitate themselves in the cold; you may also be checked for these; the underlying disease associates are different. Be proactive and read up if the results are positive. ...Read more

Dr suggested angina, stress test required. Menopausal symptoms. Low blood pressure. Raynauds phemonom. What type of angina would I most likely have?

Dr suggested angina, stress test required. Menopausal symptoms. Low blood pressure. Raynauds phemonom. What type of angina would I most likely have?

?: I'm really not sure what you have in mind. Unless you smoke or have diabetes, I'll bet you don't have angina at all! You need a stress test to see if you have evidence of coronary artery disease and to help determine if you really do have angina or not. ("angina" just means the symptom that arises from inadequate circulation to the heart muscle.) ...Read more
