Store at 2-8ºC
PRINCIPLE OF THE METHOD
Albumin in the presence of bromcresol green at a slightly acid pH,
produces a colour change of the indicator from yellow-green to
green-blue. The intensity of the color formed is proportional to the
albumin concentration in the sample1,2,3,4.
CLINICAL SIGNIFICANCE
One of the most important serum proteins produced in the liver is
albumin.
This molecule has an extraordinarily wide range of functions,
including nutrition, maintenance of oncotic pressure and transport
of Ca++, bilirubin, free fatty acid, drugs and steroids.
Variation in albumin levels indicate liver diseases, malnutrition,
skin lesions such as dermatitis and burns or dehydration1,7,8.
Clinical diagnosis should not be made on a single test result; it
should integrate clinical and other laboratory data.
ADDITIONAL EQUIPMENT
- SPIN640 / SPIN640Plus Autoanalyzer.
- General laboratory equipment.
SAMPLES
Serum or plasma, free of hemolysis1: Stability 1 month at 2-8ºC or
1 week at 15-25ºC.
REFERENCE VALUES
3,5 to 5,0 g/dL1.
These values are for orientation purpose; each laboratory should
establish its own reference range.
QUALITY CONTROL
Control sera and calibrators are recommended to monitor the
performance of assay procedures: SPINTROL H Calibrator,
SPINTROL H Normal and Pathologic (Ref. 1002011, 1002120
and 1002210).
If control values are found outside the defined range, check the
instrument, reagents and technique for problems.
Each laboratory should establish its own Quality Control scheme
and corrective actions if controls do not meet the acceptable
tolerances.
