JudyBlood specimens are typically stored in the lab for a few days to a week after testing is completed, depending on the specific requirements of the test and the lab's protocols. Once the necessary analysis and reporting is done, the specimens are typically disposed of following laboratory safety guidelines.

What are the consequence for blood specimen collection when a vacuum tube takes a very long time to fill?
If a vacuum tube takes a very long time to fill during blood specimen collection, it can lead to hemoconcentration where the blood cells become concentrated due to prolonged contact with the tube walls. This can affect the accuracy of test results as the proportion of blood cells to plasma may be altered. Additionally, prolonged exposure to air can cause changes in blood composition and potentially lead to inaccurate test results.
What electrolyte test results is affected by hemolyzed blood specimen?
Potassium levels can be falsely elevated in a hemolyzed blood specimen due to the release of intracellular potassium from damaged red blood cells. It is important to request a redraw if a specimen appears hemolyzed to ensure accurate electrolyte results.
What is possible occurrence if a blood specimen tube for hematology tests is filled correctly but not mixed long enough?
If a blood specimen tube for hematology tests is not mixed for a sufficient amount of time, the additives in the tube may not be evenly distributed in the sample. This can result in inaccurate test results, such as falsely low or high cell counts. It is important to follow proper mixing protocols to ensure accurate laboratory results.
What colour blood bottle for crp?
The blood specimen for a CRP test is usually collected in a lavender-top or clear tube with an EDTA anticoagulant. This tube is also sometimes referred to as a "purple-top" tube.
Which lab test requires tube in a slurry of ice water?
The lab test that requires the tube to be kept in a slurry of ice water is the arterial blood gas (ABG) test. This helps preserve the sample and prevent changes in pH and gases that can occur when the blood is stored at room temperature.
