Disposable Vacuum Blood Collection Container Purple Blood Collection

Classification And Application

Purple blood collection -- EDTA anticoagulant

Contains EDTA anticoagulant, in routine blood testing, the EDTA anticoagulation of the blood bulb and the morphology is less affected compared with other anticoagulants, so EDTA salt (2K,3K,2Na) is usually used as the anticoagulant. EDTA salt binds to calcium ions in the blood into chelates, thus preventing blood coagulation.
Sample type: whole blood, blood plasma
Upose:
2ml: Blood routine, mesh RBC, glycosylated hemoglobin (HBAIC), TC blood group, BNP(pacing)
5ml: pituitary, parathephrine, rinephrine, adrenal function, adrenal cortex function ATCH + COR, cortisol (COR), blood type + D antigen (synthetic blood)
Not for coagulation tests and platelet function examination or for calcium ions, potassium ions, sodium ions, iron ions, alkaline phosphatase, creatinine kinase and leucine aminopeptidase determination and PCR tests.

Structure Composition

The disposable vacuum blood collection container consists of a test tube, a plug, a cap, a label, additives (if any) and additives (if any).

Scope Of Application

Used in conjunction with disposable intravenous needles for the collection, transportation and preservation of human venous blood.

Storage Requirements

Store in a dry, well-ventilated and clean room with no corrosive gas and relative humidity above 80%

Precautions During Use

1 according to different inspection requirements, choose the appropriate blood collection tube. In case of doubt, please contact the laboratory staff at any time.

2 The sample number must be pasted on the blood collection tube, which is consistent with the number on the inspection sheet. It should be pasted on the paper label of blood collection tube, not on the glass to prevent it from falling off.

3 When taking blood, patients should relax, keep the environment warm, prevent venous contracture, and wear tourniquet for too long (now some scholars think that tourniquet should not be used as much as possible). Observe whether blood collection is smooth, and do not pat the arm, otherwise it may cause local blood concentration or activate the coagulation system.

4 The recommended order of blood collection is anticoagulant-free tube (serum tube) → separation gel/coagulant tube → heparin /EDTA tube → coagulation vessel → sedimentation tube. The main reason is that the first tube often contains tissue fluid, which is easy to cause blood coagulation and is not suitable for blood coagulation measurement; Furthermore, the serum tube is prevented from being polluted by anticoagulant.

5 After the completion of blood collection, the blood samples shall be rolled up and classified according to different inspection categories (biochemistry, immunity, routine, coagulation and erythrocyte sedimentation rate). All blood samples shall not be mixed and rolled together to avoid confusion in operation.

6 The ratio of blood to anticoagulant must be accurate, and the amount of blood collected should meet the requirements.

7 After blood collection, gently reverse the test tube and mix it 8-10 times, but do not shake violently. After blood collection, the sample should be placed vertically
