Interpretation
Provides information to assist in interpretation of the test results

Basic metabolic panel results are usually evaluated in conjunction with each other for patterns of results. A single abnormal test result could be indicative of something different than if more than 1 of the test results are abnormal. Many conditions will cause abnormal results including kidney failure, breathing problems, and diabetes-related complications.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Method Description
Describes how the test is performed and provides a method-specific reference

Sodium, Potassium, Chloride:

The ion selective electron (ISE) module indirectly measures the electromotive force (EMF) difference between an ISE and a reference electrode. The EMF of the ISE is dependent on the ion concentration of the sample. The EMF of the reference electrode is constant. An electronic calculation circuit converts EMF of the sample to the ion concentration of the sample.(Package insert: ISE Indirect Na, K, CL: for Gen 2. Roche Diagnostics; 12/2020)

 

Bicarbonate:

This is a photometric rate reaction. Bicarbonate (HCO3[-]) reacts with phosphoenolpyruvate in the presence of phosphoenolpyruvate carboxylase to produce oxaloacetate and phosphate. The oxaloacetate produced is coupled with reduced nicotinamide adenine dinucleotide (NADH) in the presence of malate dehydrogenase to produce malate and NAD(+). The consumption of NADH causes a decrease in absorbance and is monitored in the ultraviolet range of 320 to 400 nm. The rate of change is directly proportional to the concentration of bicarbonate.(Package insert: Bicarbonate reagent. Roche Diagnostics; 04/2019)

 

Anion Gap:

This is a calculated result. The following equation is used to calculate the anion gap (A gap):

A gap =Na - (Cl + HCO3[-])

 

Blood Urea Nitrogen:

This is a kinetic UV assay where urease cleaves urea to form ammonia and carbon dioxide. The ammonia formed then reacts with alpha-ketoglutarate and NADH in the presence of urease/glutamate dehydrogenase to yield glutamate and NAD(+). The decrease in absorbance, due to the consumption of NADH, is measured kinetically and is proportional to the amount of urea in the sample.(Package insert: Urea/BUN reagent. Roche Diagnostics; 12/2019)

 

Creatinine:

This enzymatic method is based on the conversion of creatinine with the aid of creatininase, creatinase, and sarcosine oxidase to glycine, formaldehyde, and hydrogen peroxide. Catalyzed by peroxidase the liberated hydrogen peroxide reacts with 4-aminophenazone and HTIB (hydroxy[tosyloxy]iodobenzene) to form a quinone imine chromogen. The color intensity of the quinone imine chromogen formed is directly proportional to the creatinine concentration in the reaction mixture.(Package insert: Creatinine Plus ver.2. Roche Diagnostics; 02/2019)

 

Calcium:

Calcium ions react with NM-BAPTA (5-nitro-5'-methyl-1,2-bis[o-aminophenoxy]ethane-N,N,N',N'-tetraacetic acid) under alkaline conditions to form a complex. This complex reacts in the second step with EDTA. The change in absorbance is directly proportional to the calcium concentration and is measured photometrically.(Package insert: Calcium Gen.2 reagent, Roche Diagnostics; 07/2019)

 

Glucose:

Glucose in the sample, in the presence of hexokinase, is converted to glucose-6-phosphate (G6P). In the presence of nicotinamide adenine dinucleotide phosphate (NADP[+]), glucose-6-phosphate dehydrogenase oxides G6P to gluconate-6-phosphate and NADPH. The rate of NADPH formation is directly proportional to glucose concentration in the sample and is measured photometrically.(Package insert: Glucose Gen.3 Reagent. Roche Diagnostics; 11/2021)
