### Patient: Doctor, I have been feeling weak and lethargic lately. My muscles are cramping, and I have been experiencing frequent episodes of tingling sensations in my hands and feet. I had a feeling this could be related to my kidneys, but I am not sure. Could you please tell me what medical tests I need to go through?
### Doctor: Based on your symptoms, you may be suffering from hypocalcemia, which means your body has a lower than normal level of calcium. To determine the cause and severity of your condition, we will need to conduct a series of tests, including a complete blood count, kidney function tests, radiographic imaging procedure, and glucose measurement. In addition, we may have to perform an electrocardiogram to check on the health of your heart. Intravenous fluid replacement may also be needed to bring up your calcium levels to a safe level.
