What is the cause of blood clotting during blood collection?

Coagulation, Thrombosis, Hemostasis

Blood coagulation during collection, namely the premature coagulation of blood in a test tube or blood collection tube, can be attributed to a multitude of factors. These encompass blood collection techniques, contamination of test tubes or blood collection tubes, inadequate or inappropriate anticoagulants, slow blood extraction, and obstructed blood flow. In the event of coagulation during blood collection, it is crucial to seek medical assistance promptly.

Causes of Coagulation during Blood Collection

1. Blood Collection Techniques:

During blood collection, if the needle is inserted or removed too rapidly, it might lead to blood coagulation within the needle or test tube.

2. Contamination of Test Tubes or Blood Collection Tubes:

The contamination of blood collection tubes or test tubes, such as the presence of bacteria or residual blood coagulation factors in the tubes, can trigger blood coagulation.

3. Insufficient or Inappropriate Anticoagulants:

The inadequate or improper addition of anticoagulants like EDTA, heparin, or sodium citrate in the blood collection tube will result in blood coagulation.

4. Slow Blood Extraction:

If the blood extraction process is too slow, causing the blood to remain in the blood collection tube for an extended period, blood coagulation may occur.

5. Obstructed Blood Flow:

When blood flow is obstructed during blood collection, for example, due to the bending or blocking of the blood collection tube, blood coagulation is likely to happen.

Ways to Avoid Coagulation during Blood Collection

1. Use of Appropriate Blood Collection Tubes:

Select blood collection tubes that contain the correct type and concentration of anticoagulant.

2. Proper Labeling of Blood Collection Tubes:

Clearly label the blood collection tubes to ensure proper handling in the laboratory.

3. Preparation before Blood Collection:

Ensure that all tools and equipment are clean and sterile prior to blood collection.

4. Blood Collection Technique:

Employ aseptic techniques during blood collection to guarantee the sterility of needles and blood collection tubes. Be gentle when collecting blood to avoid damaging blood vessels.

5. Blood Sample Processing: Immediately after blood collection, invert the blood collection tube several times to ensure the full mixing of the anticoagulant with the blood. If necessary, the blood sample can be centrifuged promptly after collection to separate the plasma.

For patients at risk of abnormal coagulation function, it is essential to conduct an advance evaluation and take corresponding preventive measures.

Analyzer Introduction

Fully Automated Coagulation analyzer SF-9200 (https://www.succeeder.com/fully-automated-coagulation-analyzer-sf-9200-product) can be used for clinical test and pre-operative screening. Hospitals and medical scientific researchers also can use SF-9200. Which adopts coagulation and immunoturbidimetry, chromogenic method to test the clotting of plasma. The instrument shows that clotting measurement value is the clotting time (in seconds). If the test item is calibrated by calibration plasma, it can also display other related results.

The product is made of sampling probe movable unit, cleaning unit, cuvettes movable unit, heating and cooling unit, test unit, operation-displayed unit, LIS interface (used for printer and transfer date to Computer).

Technical and experienced staffs and analyzers of high quality and strict quality management are the guarantee of manufacture of SF-9200 and good quality. We guarantee each instrument inspected and tested strictly. SF-9200 meets China national standard, industry standard, enterprise standard and IEC standard.
