Test ID: A871
Albumin makes up more than half of the total protein in serum. Thyroid hormone, corticosteroids, growth hormone, and insulin can increase albumin synthesis. Fasting, protein-deficient diets, liver disease, and intestinal malabsorption syndromes can cause a decrease in albumin synthesis.
How to order a test
What is Included?
Measurement of albumin levels in a blood sample by colorimetric methodology.
1 – 3 business days
The turnaround time is not guaranteed. The average turnaround time is 1 – 3 business days from the date that the sample arrives at the laboratory. Shipping time for the sample is not included. Additional time is required if the case requires confirmatory or reflex testing, or if the sample is insufficient, or if a recollection is required.
Additional Information and Resources
Preparation Before Specimen Collection
50 μL in a microtainer
Microtainer (regular blood tube)
This test requires a blood sample from a finger prick. All supplies for sample collection are provided in the kit.
- First wash and dry hands. Warm hands aid in blood collection.
- Clean the finger prick site with the alcohol swab and allow to air dry.
- Use the provided lancet to puncture the skin in one quick, continuous and deliberate stroke.
- Wipe away the first drop of blood.
- Massage hand and finger to increase blood flow to the puncture site. Angle arm and hand downwards to facilitate blood collection on the fingertip.
- Drip blood into the microtainer tube.
- Dispose of all sharps safely and return sample to the laboratory in the provided prepaid return shipping envelope.
NOTES: Avoid squeezing or ‘milking’ the finger excessively. If more blood is required and blood flow stops, perform a second skin puncture on another finger. Do not touch the fingertip.
Maintain specimen at temperatures between 2°C and 30°C during storage and transport.
Blood samples can be refrigerated or kept at room temperature for up to 7 days.
Causes for Rejection
- Incorrect or incomplete patient identification
- Incorrect specimen collection
- Inappropriate storage and transport conditions
- Incorrect specimen volume
To measure albumin levels in a blood sample for the evaluation of nutritional status, liver disease, renal disease, and other chronic diseases.
Thyroid hormone, corticosteroids, growth hormone, and insulin can increase albumin synthesis. Fasting, protein-deficient diets, liver disease, and intestinal malabsorption syndromes can cause a decrease in albumin synthesis. Accelerated losses of albumin can also occur due to nephrotic syndrome and severe burns because skin is an extra storage pool for albumin.
