Product Details
Red cap plasma separation tube vacuum blood collection tube no
additive tube
Product description
No additive tubes, also known as plain tubes or serum tubes, are
essential components in phlebotomy and blood collection processes.
Here is a detailed description of these specialized medical tubes:
Purpose and Functionality:
- No additive tubes are sterile containers used for collecting blood
samples without any anticoagulants, preservatives, or clot
activators.
- They are primarily employed for serum separation, coagulation
studies, blood chemistry tests, and various diagnostic
investigations.
- Design and Composition:
- Made from transparent glass or plastic, these tubes have a closed
top with a rubber stopper or a plastic cap for secure sealing.
- The absence of additives ensures that the blood sample remains in
its natural state without any interference from external
substances.
- Available in different sizes, typically color-coded to indicate the
type of additive-free tube (e.g., red or gold tops for serum
collection).
Key Features:
- Clot Activator-Free: No additives in the tube prevent the blood
from clotting, allowing for serum separation by natural coagulation
processes.
- Sterile Interior: Ensures that the collected sample remains
uncontaminated and suitable for diagnostic testing.
- Clear Visibility: Transparent construction allows for easy
observation of the blood sample and facilitates visual inspection
for quality control.
- Secure Closure: The stopper or cap provides a leak-proof seal,
preventing sample spillage or contamination.

Applications:
- Serum Testing: Used for collecting blood samples for chemistry
panels, liver function tests, lipid profiles, and other serum-based
analyses.
- Coagulation Studies: Suitable for tests that require natural
clotting processes to evaluate clotting factors and coagulation
parameters.
- Blood Bank Procedures: Employed in blood banking for serological
tests, blood typing, and cross-matching.
- Usage Guidelines:
- Collect blood samples using aseptic techniques to prevent
contamination.
- Invert the tube gently to mix the blood with the clot activator, if
necessary, for serum separation.
- Label the tube accurately with patient information and specimen
details for proper identification.
Benefits:
- Ensures accurate and reliable test results by maintaining the
integrity of the blood sample.
- Facilitates serum separation without the need for additional
processing steps.
- Reduces the risk of sample contamination or interference from
additives.
- Streamlines blood collection processes in laboratories and
healthcare facilities.
- No additive tubes play a crucial role in blood collection and
diagnostic testing, providing healthcare professionals with a
reliable and uncontaminated medium for serum-based analyses and
coagulation studies.
FAQ
1.Which tube is used for plasma separation?
Following centrifugation, it is important to immediately transfer
the liquid component (plasma) into a clean polypropylene tube using
a Pasteur pipette.
2.What is the red top tube used for?
Red-top tube: Contains no anticoagulant or preservative. Use: Serum
or clotted whole blood. Serum must be separated from cells within
45 minutes to two hours depending on the test(s).
3.What is the red cap vial used for?
Red-top tube, plastic
This tube is a plastic Vacutainer containing a clot activator but
no anticoagulants, preservatives, or separator material. It is used
for collection of serum for selected laboratory tests as indicated.
4.What is a red cap test tube used for?
Red Top Blood Tube, Plain and Pro-Coagulation Tubes - Hawach
Chemistry tests: Red top tubes are commonly used for a wide range
of chemistry tests, including liver function tests, kidney function
tests, lipid profile, blood glucose levels, electrolyte analysis,
and many other biochemical assays.
5.What is the difference between red top and tiger top?
Red Top: Does not contain an anticoagulant. This tube is used for
collecting serum or clotted whole blood specimens. This tube should
be used for all drug levels. Serum Separator Tube (SST) (Tiger
Top): Does not contain an anticoagulant but contains a clot
activator and serum separator gel.
