Blood Chemistry Profile

Laboratory Test

What is the test?

A blood chemistry profile measures different chemical aspects of your blood.

This lab test is routinely used to measure: 

  blood glucose for diabetes

  urea, nitrogen, and creatinine for kidney function

  sodium, potassium, chloride, and CO-2 to evaluate electrolytes and fluid balance

  calcium, to help determine bone density and function

  liver function.

Blood chemistry profiles can also include a special lipid metabolism profile for people with elevated cholesterol, to measure triglycerides, HDL cholesterol, and LDL cholesterol.

How do I prepare?

Most blood chemistry profiles require 12-hour or overnight fasting, which means you should refrain from eating or drinking for 12 hours prior to the blood draw. Check with your doctor to see whether you should abstain from any of your regular medications prior to the test, because they may interfere with the test results.

How is the test done?

A blood chemistry profile requires a needle stick, typically in the arm, to draw a sample of your blood for analysis.

How and when will I get my test results?

Lab test results are usually available either the same day or the following day. The results will be sent directly to your doctor, who will share them with you.
