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.
