Hello!
Are you ready for a quiz on routine lab numbers? Lol😊 The previous post reviewed the purpose of each of the 20
lab markers/ measurements in an SMA 20 Panel (Sequential Multiple Analyzer
panel). This is also known as CMP (Comprehensive Metabolic Panel). The SMA 20
or CMP panel measures key electrolytes, kidney and liver function markers,
glucose, and proteins. Too often, I hear health care providers just ramble the
names of these tests with numbers, expecting the patient to understand exactly
what they are talking about. My goal is for you to understand the meaning of
these markers and the significance of any abnormal numbers. We cannot make a
change if we do not fully understand what our targets are. 


Normal
adult reference ranges are provided below for general educational purposes.
Ranges may vary slightly in different labs and publications.

Glucose
(Fasting)70–100mg/dL , Sodium (Na+) 136–145mEq/L, Potassium (K+) 3.5–5.0 mEq/L, Chloride
(Cl–) 95–105 mEq/L,CO2 (Bicarbonate)22–28mEq/L. BUN 7–20 mg/dL, Creatinine
0.6–1.2 mg/dL. Calcium (Total) 8.4–10.2mg/dL, Phosphorus 3.0–4.5 mg/dL. Magnesium
1.5–2.0 mg/dL, Total Protein 6.0–7.8 g/dL, Albumin 3.5–5.5 g/dL, Globulin
2.3–3.5 g/dL, ALT(Alanine Aminotransferase) 10–40 U/L , AST (Aspartate Aminotransferase)12–38 
 I hope that you feel better
equipped to ask your healthcare providers any questions that you may have
about your SMA 20 lab results.
