What the laboratory says this test is for

This panel comprises a group of 4 tests that provide information on an individual's electrolytes, acid-base, and water balance. The panel is usually ordered during hospital and emergency room admission to help diagnose a range of conditions as well as monitor certain conditions or treatments that affect electrolyte balance [1].Symptoms and signs of electrolyte, acid-base, and water imbalance may include dehydration, edema, vomiting, weakness, confusion, and cardiac arrhythmias. These imbalances may be associated with kidney diseases, respiratory distress, and metabolic disorders [1]. The results of the panel components are usually evaluated jointly for patterns. The section below outlines the roles of the analytes assessed with this panel [1].Sodium: An electrolyte that plays a central role in maintaining the normal distribution of water and appropriate pressure to assure that substances do not leak from cells and organs. Sodium measurements are useful in the diagnosis and treatment of diseases involving electrolyte imbalance.Potassium: An electrolyte that is essential for proper muscle and nerve function and helps keep the balance of fluids. Potassium measurements are useful in assessing electrolyte balance in the diagnosis and treatment of conditions characterized by low or high blood potassium levels.Chloride: An electrolyte that helps maintain volume, acidity, and electrical neutrality of the body fluids. Chloride measurements are useful in the diagnosis and treatment of electrolyte and metabolic disorders, such as cystic fibrosis and diabetic acidosis.Carbon dioxide (bicarbonate): A type of blood gas used to evaluate the total carbonate buffering system and acid-base balance. Carbon dioxide is generally evaluated with other common electrolytes; the measurements are useful in the diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance.References1.

What the laboratory says this test is for

This panel comprises a group of 4 tests that provide information on an individual's electrolytes, acid-base, and water balance. A calculated anion gap is included to help diagnose metabolic acidosis. The panel is usually ordered during hospital and emergency room admission to help diagnose a range of conditions as well as monitor certain conditions or treatments that affect electrolyte balance [1].Symptoms and signs of electrolyte, acid-base, and water imbalance may include dehydration, edema, vomiting, weakness, confusion, and cardiac arrhythmias.

Carbon dioxide is generally evaluated with other common electrolytes; the measurements are useful in the diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance.Anion gap (electrolyte balance): Calculated difference between serum anion and cation levels. Decreased anion gap may be caused by low albumin level; increased anion gap may be caused by excess anions of acids, such as sulfate, lactate, and ketone anions.References1. Rao LV, et al.

Specimen

Fasting
Not stated as required

What the laboratory says this test is for

This panel is usually ordered to monitor patients with chronic kidney disease (CKD) or as part of a health examination for individuals at high risk of developing kidney diseases [1].Kidney disease is more likely to develop in individuals with certain conditions, such as high blood pressure, diabetes, heart disease, and a family history of kidney disease. Early symptoms of kidney diseases are often non-specific. This panel is commonly ordered during wellness checks and emergency-room admissions when symptoms and signs are suggestive of kidney diseases. National Kidney Foundation recommends a kidney profile containing estimated glomerular filtration rate and albumin-creatinine ratio for detecting and monitoring CKD [1].The results of this test should be interpreted in the context of pertinent clinical and family history and physical examination findings.References1.

What the laboratory says this test is for

This panel comprises a group of 7 specific tests that provide information on the status of an individual's blood electrolytes, glucose levels, kidney status, and acid-base balance. The panel is usually ordered as part of a routine health examination or physical [1].The Basic Metabolic Panel is also commonly ordered during hospital and emergency room admission, and to monitor the metabolism and vital signs of hospitalized individuals with conditions, such as hypertension, who are being treated with diuretics or other appropriate interventions. [1].Significant changes in electrolytes, acid-base balance, renal function, and blood glucose may be associated with kidney failure, respiratory distress, and impaired cognitive status. Changes in sodium, potassium, and calcium alter the excitability of neurons, cardiac, and skeletal muscles that can produce arrhythmias, weakness, and spasms/tremors [1].The results of the panel components are usually evaluated jointly for patterns.

What the laboratory says this test is for

This panel comprises a group of 8 specific tests that provide information on the status of an individual?s blood electrolytes, glucose levels, kidney status, and acid-base balance. The panel is usually ordered as part of a routine health examination or physical [1].The Basic Metabolic Panel is also commonly ordered during hospital and emergency-room admission, and to monitor the metabolism and vital signs of hospitalized individuals with conditions, such as hypertension, who are being treated with diuretics or other appropriate interventions. [1].Significant changes in electrolytes, acid-base balance, renal function, and blood glucose may be associated with kidney failure, respiratory distress, and impaired cognitive status. Changes in sodium, potassium, and calcium alter the excitability of neurons, cardiac, and skeletal muscles that can produce arrhythmias, weakness, and spasms/tremors [1].Basic metabolic panel test results are usually evaluated in conjunction with one another 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 can cause abnormal results, including kidney failure, respiratory distress, and diabetes-related complications [1].The section below outlines the roles of the analytes assessed with this panel [1].Sodium: Plays a central role in maintaining the normal distribution of water and osmotic pressure.Potassium: Essential for proper muscle and nerve function.Chloride: Helps keep the balance of fluids, maintain blood volume, stabilize blood pressure, and balance the pH of body fluids.CO2 (carbon dioxide, bicarbonate): Used to evaluate the total carbonate buffering system and acid-base balance.Glucose: A critical energy source for cells and organs. Used to diagnose diabetes and hypoglycemia.Calcium: Essential for nerve, muscle, and heart functions and bone formation.BUN (blood urea nitrogen): Evaluation of kidney function.Creatinine: Useful for diagnosis of renal insufficiency and estimation of glomerular filtration rate.References1.
