A chemistry screen is a blood test that measures the levels of several substances in the blood (such as electrolytes).
Normal values vary from lab to lab and depend on which tests were included in your chemistry screen. Results are usually available in 1 to 2 days.
Many conditions can change chemistry screen test levels. Your doctor will talk with you about any abnormal results that may be related to your symptoms and medical history. For more information about normal and abnormal values, see:
