Urine TT means urine ketone bodies, and positive urine TT means positive urine ketone bodies. Ketone bodies are an acid produced by fat metabolism. Under normal circumstances, there are very few ketone bodies in the body, and they are generally not detected in routine examinations, so the qualitative examination of normal people shows negative, only when there is insufficient glucose in the body or when there is diabetes or glucose metabolism disorders, when the body cannot use glucose as a source of energy, it will use fat decomposition to produce energy, and ketone bodies will appear. When ketone bodies accumulate, ketone bodies will appear in the urine, i.e. positive urine ketone bodies. A positive urine ketone body is a qualitative test. The presence of ketone bodies in the urine is generally indicated as (+), (++), (++++), and the more plus signs, the more serious the accumulation of ketone bodies in the body. Starvation and various causes of impaired glucose metabolism can lead to increased fat decomposition in the body, such as women with early pregnancy, if the pregnancy reaction is more serious, eating too little, or even can not eat, vomiting, can lead to hypoglycemia, then the body can not use glucose as a source of energy, only use fat decomposition to provide energy, resulting in excessive production of ketone bodies in the body, urine ketone body positive, ketosis Acidosis. In addition, there are also more common patients with diabetic acidosis, which is a more serious complication of diabetes mellitus due to the impaired glucose metabolism, resulting in the rapid production of ketone bodies in the body, and the occurrence of ketonemia, followed by urinary ketones. Positive urine ketone bodies are an abnormal phenomenon, so you must go to the hospital in time, and try to eat if you can, but if you can’t, you can give intravenous fluids to replenish energy and correct acidosis, so as not to affect the health of the organism.
