Metabolic / Electrolytes
Also known as: blood creatinine, serum creatinine, urine creatinine
Symptoms like swelling in hands/feet, dry skin, itching, fatigue, changes in urination, bloody/foamy urine, loss of appetite, muscle cramps, nausea/vomiting, shortness of breath, or trouble thinking clearly warrant contacting your clinician.
This test checks the amount of creatinine in your blood or pee. Creatinine is a leftover from your muscles working. Your kidneys usually clean this waste out of your body.
Your doctor wants to check how well your kidneys are working. This is especially true if you have signs of kidney problems. It's also true if you have health issues that make kidney problems more likely.
Creatinine levels can vary by lab, and normal ranges depend on factors like muscle mass, diet, age, and activity level. Your doctor will interpret your results in the context of your overall health.
