Renji Blood Collection Tubes made of PET and color coded based
on the appropriate additive and International Standards
Renji Blood Collection Tubes are made of PET and color coded
according to the
appropriate additive and International Standarts (ISO6710). Each
tube has it own
vacuum state for collection of blood with proper quantity and
marked on label for
blood collection and additives in the tube.
【APPLICATIONS】
Vacuum Blood Collection Tubes are used to transport and process
blood for testing serum,
plasma, or whole blood in the clinical laboratory. According to
different testing, Renji tubes
can be divided into 10 types. That’s Plain Tube, Clot Activator
Tube, Clot Activator& Gel Tube,
Glucose Tube, EDTA&Gel Tube, EDTA tube, Coagulation Tube and
ESR tube, Thrombin-based
Clot Activator&Gel.
Used for collection and storage of blood samples in biochemical,
immune, serum, and other
clinical medical tests. Whether glass tube or plastic tube, its
inner wall is extremely smooth,
can effectively avoid blood cells attached to the wall, minimize
the specimen in vitro
hemolysis.
Our blood collection tubes allow ease-of-use and help to ensure a
quality blood
sample is collected.
Renji Medical offers glass blood collection tubes for a wide range
of laboratory
procedures including hematology, serology, toxicology, blood bank,
routine coagulation
and certain chemistry procedures.Tubes are sterilized by gamma
radiation.

The most commonly used blood collection tubes
【CHOOSING THE RIGHT BLOOD COLLECTION TUBES】
Whether you’re collecting your samples in-house or through a
clinic, hospital, or pathology
center, you’ll need to have a good idea of what kind of blood
collection tubes suit your purposes.
The first thing to check is your protocol—for example, some ELISAs
will specify the types of
samples you can and can’t use.
But what if your protocol doesn’t specify, or you’re adapting a
method from another system,
or you just want to make sure you’re storing the best type of
sample for future not-yet-defined
analyses? Hopefully, I can help you start to find your way around
all those differently colored
tubes.
A quick note about those cap colors before we begin: I’ve listed
them below, and the
color-coding system is generally pretty consistent, but I can’t
promise the colors are the
same in every company producing blood collection tubes, so always
check first!
Serum Tubes
The first thing to figure out is whether you are after serum, or
whether you’ll need to stop
the blood from clotting.
Don’t get serum confused with plasma—while they’re both the liquid,
cell-free part of the
blood that can be obtained by centrifugation, the key difference is
that serum is the product
of blood that has been allowed to clot, while in a plasma sample,
the dense cells are simply
spun to the bottom.
Serum is, in simple terms, what remains in the blood after it
clots: a cell-free liquid that is
also depleted of coagulation factors. It can be a good, stable way
of measuring the blood’s
proteins, lipids, hormones, electrolytes, and so on. Many of these
markers can be stored
for days in the fridge, or frozen down and measured in batches
later.
- Serum (clot activator) tubes (color dependent on brand: BD is
commonly gold but
also red, Greiner is red). These tubes have silica particles, which
activate clotting.
Some also have a gel to separate the serum. Those without the
separating gel are
potentially more useful in sensitive diagnostic testing. If you’re
looking for a
protein that isn’t involved in coagulation, this is a good place to
start.
- Thrombin-based clot activator tubes (orange). Although the
silica-coated tubes
clot within about 30 minutes, the orange tubes clot within 5
minutes. They’re mainly
used clinically for tests that are needed especially quickly.
However, some of the serum
components are a little less stable in these tubes.
Anticoagulant Tubes
This is the category to consider if you need cells or plasma (a
cell-free liquid that still contains
coagulation factors).
EDTA (Purple)
EDTA prevents clotting by chelating calcium, an essential component
of coagulation. This is
your basic hematology tube (by which I mean identifying and
counting blood cells,
blood typing, etc).
Plasma stored from EDTA-treated blood can also be used to measure
most proteins, and
genetic
material can easily be stored from EDTA buffy coats (the interface between
the red
cells and the plasma after centrifugation, containing white cells
and platelets).
Note: these tubes contain either K2EDTA or K3EDTA.
Sodium Citrate (Light Blue)
For coagulation and platelet function tests. Like EDTA, citrate
acts by removing calcium from
the blood. Unlike EDTA, it’s reversible—so calcium can be added
back to study coagulation
under controlled conditions. Citrated plasma is also used to
measure coagulation-relevant
factors.
It’s worth noting that a citrate tube should not be the first type
of tube filled after
venepuncture—the first few mL of blood drawn will be a bit
activated. If you only need
samples collected in citrate blood collection tubes for your
project, then you should
collect a discard tube first.
Also, note that different concentrations of citrate are available
from different companies.
CTAD (Also Light Blue)
CTAD stands for citrate, theophylline, adenosine, and dipyridamole.
These aren’t very
commonly used but are worth knowing about—they prevent ex vivo activation of your
platelets, making them useful for some more sensitive platelet
function and coagulation
studies. Note that CTAD is light-sensitive, so keep these guys in
the dark.
Lithium/Sodium Heparin (Green)
Similar in use to serum clot activator tubes, but suitable for
tests in plasma rather than
serum. Like the serum tubes, heparin tubes can also come with a
separating gel. Heparin
acts by inhibiting thrombin formation. Note: if your endgame is
PCR, you should know
that heparin is particularly known to interfere with PCR reactions.
However, whichever anticoagulant you choose, you may need to allow
for it in your
reaction mix.
Sodium Fluoride (Color Dependent on Brand: BD is Grey, Greiner is
Black)
Sodium fluoride is an antiglycolytic agent, so these tubes are used
for glucose and lactate
testing. They also contain an anticoagulant (there are different
types available).
Acid Citrate Dextrose—ACD (Yellow)
These ones are not common, but they are used for blood and tissue
typing and DNA analysis.
Sodium Polyanethol Sulfonate—SPS (Also Yellow)
SPS stabilizes bacterial growth. Useful for microbiology.
For more specific purposes, there are more blood collection tubes
out there, but,
hopefully, this has given you a handle on where to start. Good
luck, and welcome to
the world of—let’s be honest—feeling just a little bit like a
vampire.
Step of Correctly Preparing High-Quality Serum with Gel/Clot
Activator Tube
Step1:Place patient's arm in a downward position and clean
venipuncture sire with alcohol；
Step2:Apply tourniquet；
Step3:Remove the upper cover of the needle and assemble the needle
in the holder；
Perform venipuncture with arm downward and tube stopper upper-most；
Step4-5:Push tube onto the needle, puncturing stopper diaphragm；
Step 6； Release tourniquet as soon as blood appears in a tube and
remove the tube from
the holder when the first tube has filed to its stated volume and
blood flow ceases；
Step7:Turn the filed tube upside-down and return it to upright
positions and repeat this
inversion according to different additive performance；
Step8:Place succeeding tubes in the holder, puncturing diaphragm to
begin to follow, see
Recommended Order of Draw；
Step9:As soon as blood stops flowing in the last tube, remove the
tube from the holder
and remove the needle from Vein, applying pressure to puncture site
with the dry sterile
swab until bleeding stops；
Step10:Dispose the needles into Sharps Disposal Containers
according to related policies
and guidelines.
