Lavender/Purple Stopper Vacuum Tubes for Blood Sample
Centrifugation
Product Description
Blood sample tubes are tools for collecting, storing and processing
blood, and are widely used in medical testing and clinical
diagnosis. In order to ensure the accuracy and efficiency of blood
testing, the type of blood collection tube and the choice of
additives are crucial. The following will introduce the types of
blood sample tubes and their specific uses in detail:
Red top blood collection tubes
Use: These blood collection tubes do not add any anticoagulants or
additives, and are mainly used for serological tests, such as
biochemical tests, immunological tests, etc.
Features: Red top blood collection tubes allow blood to be
separated into serum after coagulation. Serum does not contain
coagulation factors and is suitable for the detection of most blood
proteins, hormones and electrolytes.
Green top blood collection tubes
Use: Green blood collection tubes containing heparin anticoagulants
are mainly used for blood gas analysis, electrolyte testing,
hematocrit and emergency biochemical testing.
Features: Heparin has an anticoagulant effect and can prolong the
coagulation time of the specimen. It is suitable for tests that
require whole blood or plasma samples.
Purple/pink top blood collection tubes
Use: Blood collection tubes containing EDTA anticoagulants are
mainly used for blood cell counting, blood typing and blood
pathology tests, such as blood routine tests and blood sugar tests.
Features: EDTA can prevent blood coagulation by chelating calcium
ions, which is very important for blood cell counting and blood
typing.
Blue top blood collection tube
Purpose: Mainly used for coagulation function tests, such as
thrombin time, partial thromboplastin time and fibrinogen
determination.
Features: 3.2% or 3.8% sodium citrate anticoagulant is added to the
blood collection tube, which can remove calcium from the blood and
thus play an anticoagulant role.
Yellow top blood collection tube
Purpose: Yellow top blood collection tube containing anticoagulant
EDTA is mainly used for blood pathology detection, such as blood
routine, blood sugar detection, etc.
Features: EDTA can prevent blood coagulation by chelating calcium
ions, which is very important for blood cell counting and blood
typing.
Black top blood collection tube
Purpose: Mainly used for erythrocyte sedimentation rate
determination.
Features: Contains 3.2%-3.8% sodium citrate anticoagulant, and the
volume ratio of anticoagulant to blood is 1:4, which helps to
measure the erythrocyte sedimentation rate.
In summary, the choice of blood sample tubes has a significant
impact on the accuracy of experimental results. Different types of
blood collection tubes and additives determine the specific use and
detection methods of blood samples. Correctly selecting the type of
blood collection tube can not only improve experimental efficiency,
but also ensure the accuracy and reliability of test results.
Laboratory staff should fully understand the characteristics and
applicable scenarios of different blood collection tubes in order
to better conduct experimental design and data interpretation.
