Sometimes the patient may have an allergic reaction to the blood transfused to him, and this may happen even when he is given the correct blood group. These allergic reactions range from mild to serious. Signs of allergic reactions include anxiety, back or chest pain, increased heart rate, low blood pressure, breathing disorder, fever, shivering, and nausea. Both fever and chills are the most frequent transfusion reactions and resolve without treatment or causing complications. Chronic shortness of breath, red color of urine, fever, and loss of consciousness may be an indication of chronic reactions that threaten the patient’s life.
