Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
The difference in units is attributed to the difference in the way that blood solutes are measured in the laboratory versus the way they are calculated. The laboratory value measures the freezing point depression, properly called osmolality while the calculated value is given in units of osmolarity. Even though these values are presented in ...
The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations.
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
Hypophosphatemia is diagnosed by measuring the concentration of phosphate in the blood. Concentrations of phosphate less than 0.81 mmol/L (2.5 mg/dL) are considered diagnostic of hypophosphatemia, though additional tests may be needed to identify the underlying cause of the disorder. [9]
Red blood cell indices are blood tests that provide information about the hemoglobin content and size of red blood cells. Abnormal values indicate the presence of anemia and which type of anemia it is.
It is simple to measure serum creatinine, and it is the most commonly used indicator of renal function. [6] A rise in blood creatinine concentration is a late marker, observed only with marked damage to functioning nephrons. The test is therefore unsuitable for detecting early-stage kidney disease.
Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.
