Why should you wait for a specimen collected in a red stopper tube be clotted before centrifuging?
Specimens collected in a red stopper tube typically contain no additives, allowing for the blood to clot naturally. Waiting for the specimen to clot ensures that the solid components, such as blood cells, separate from the liquid component, or serum, during centrifugation. If the specimen is centrifuged too early, it may result in the presence of fibrin and other cellular elements in the serum, potentially affecting test results. Proper clotting time is essential for accurate laboratory analysis.

What is automatic stopper?
is the part of the microscope that automatically stop at a given time usually to keep the distance of the body tube from the specimen.
What would occur if an orange shield tube is collected before a light blue stopper?
If an orange shield tube is collected before a light blue stopper, it may lead to improper sample handling or contamination. Depending on the context, this could affect the validity of the results, as the order of collection often ensures that additives in the tubes interact correctly with the sample. Additionally, it might compromise the integrity of the specimen, potentially skewing diagnostic outcomes. Following proper protocol for sample collection is crucial for accurate testing.
If a grey stopper tube is collected before a lavender shield tube what can occur?
If a grey stopper tube is collected before a lavender shield tube, contamination from the additives in the grey stopper tube may lead to inaccurate results in the lavender shield tube, especially for analytes sensitive to contamination or carryover effects. It is important to follow the recommended order of draw during blood collection to prevent such issues.
Why must the container be stoppered for the gas to be collected?
The stopper prevents the gas from escaping into the surroundings, allowing it to be collected efficiently within the container. It also helps to ensure that the gas sample remains uncontaminated by outside air or particles. Additionally, a closed system with a stopper allows for accurate measurement and analysis of the collected gas.
What color stopper tube is used to collect a blood specimen for a prothrombin time test?
A light blue stopper tube is typically used to collect blood specimens for prothrombin time tests. The light blue stopper indicates the presence of sodium citrate as an anticoagulant, which is important for accurate testing of clotting factors.
What happens if I orange shield tube is collected before a light blue stopper shield in phlebotomy?
In phlebotomy, if an orange shield tube is collected before a light blue stopper tube, it can lead to inaccurate results in coagulation tests. The orange tube typically contains a gel separator for serum testing, which may contaminate the blue tube's citrated plasma sample, potentially affecting the measurement of clotting factors. To ensure accurate results, the light blue tube should always be collected first when performing tests that require it.
