Hello, male 33 years old. Had some blood and urine work done. All came back normal. Thyroid, glucose , WBC , RBC , Cholesterol , Kidney and Liver function. They found a small about of RBC in urine, Dr mentioned 3-5 and urine was very concentrated. Dr wants to repeat the test in a few weeks. Given everything else is normal she feels this is due to dehydration. Too much coffee and alcohol and not enough water. Told me not to worry. Does this sound about right?
