A high or low anion gap is a calculated clue from an electrolyte or metabolic panel. Learn what it can mean, why lab ranges vary, when it may be urgent, and what follow-up tests often help clarify the result.
The CO2 or bicarbonate blood test is usually part of a metabolic or electrolyte panel. Learn what it measures, normal ranges, high and low results, preparation, limitations, and cost considerations.
A high or low chloride result usually reflects a fluid, salt, kidney, medication, or acid-base balance issue. Learn how to interpret chloride with sodium, potassium, bicarbonate/CO2, and symptoms.
A chloride blood test checks an important electrolyte involved in fluid and acid-base balance. Learn why it is ordered, how to prepare, what results may mean, and what to ask next.
Self-pay chloride blood testing can cost under $30 with fees included, but panels that include chloride may offer better value. Compare total prices, mandatory fees, and when to choose a standalone test versus an electrolyte panel or CMP.
A high or low potassium result can reflect kidney function, medications, fluid loss, hormone conditions, diet, or sample handling. Learn how potassium results are interpreted and when to seek care.
A potassium blood test checks an important electrolyte involved in nerve, muscle, kidney, and heart function. Learn why it is ordered, how to prepare, and what high or low results may mean.
Compare potassium blood test cost without insurance, including direct-order lab prices, mandatory fees, BMP/CMP alternatives, preparation, and when a broader panel may be a better value.
A high or low sodium blood test result usually reflects a water-balance problem, medication effect, kidney or hormone issue, or fluid loss—not simply how much salt you ate. Learn what sodium results can mean, when they are urgent, and what to ask next.
A sodium blood test checks electrolyte and fluid balance. Learn what it measures, how to prepare, what low or high sodium may mean, and when to seek care.
