Clotting Factors

Clotting factors are special proteins in your blood. They help stop bleeding when you get hurt. When you have a cut, these proteins work together to make a clot. The clot seals the wound. In laboratory tube collection, you need to know how these factors work. If you do not handle blood the right way, clotting can happen inside the tube. This can ruin your plasma and make your test results wrong.


The most important clotting factors during blood collection are:

  • Fibrinogen (Factor I): Makes threads that hold the clot together.

  • Prothrombin (Factor II): Turns into thrombin, which helps make the clot.

  • Tissue factor (Factor III): Starts the clotting process when blood leaves the vessel.

  • Calcium ions (Factor IV): Help other coagulation factors stick to the right places.

  • Other factors (V, VII, VIII, IX, X, XI, XIII): Help build a strong clot.


You need to keep these coagulation factors active and stable. This is important during laboratory tube collection. If you do not, your plasma may not show true blood coagulation activity. Bad blood collection or waiting too long can cause clotting. This uses up the factors and lowers plasma quality. Automated blood collection machines from Lingwen Intelligent help stop these problems. They make the collection process the same every time and protect the plasma.


Anticoagulant Role

Anticoagulants are chemicals that stop blood from clotting. You add an anticoagulant to the tube before collecting blood. This keeps the coagulation factors from starting the clotting process. The anticoagulant effect is very important for tests that need plasma. These include coagulation studies and blood chemistry tests.


You use different anticoagulants for different tests. For example, heparin works by boosting antithrombin. This blocks thrombin and factor Xa. It stops the blood coagulation cascade and keeps plasma clear. Citrate binds calcium ions, which are needed for coagulation. This also stops clotting. EDTA stops blood coagulation by binding calcium too. Each anticoagulant effect helps you get the right plasma for your test.


Automated blood collection machines mix blood and anticoagulant right away. This stops tiny clots from forming, even if you cannot see them. If you use the wrong amount of anticoagulant, your test results may be wrong. Too much anticoagulant can make clotting times look longer than they really are. Too little can let clotting start. This uses up coagulation factors and changes the plasma. Machines from Lingwen Intelligent keep the blood-to-anticoagulant ratio correct. They also mix the tube well, so your laboratory tube collection stays reliable.

Tip:Always check that you use the right blood collection method. Make sure you use the correct anticoagulant for your test. This helps protect the plasma and gives you accurate results.

It is very important to understand clotting factors, anticoagulants, and the whole coagulation process. When you use a modern blood collection machine, you keep your laboratory tube collection safe. Your plasma stays high quality. Your blood coagulation activity is measured the right way. This knowledge helps you do better in any healthcare or laboratory job. It is especially helpful when you use Lingwen Intelligent’s advanced equipment.


Types of Anticoagulants

Types of Anticoagulants

When you collect blood, you must pick the right anticoagulant. There are three main types in blood collection machines: EDTA, citrate, and heparin. Each type works differently and is used for certain tests. The table below lists common anticoagulants, their tube colors, uses, and how they work:

Anticoagulant

Tube Color

Primary Use

Mechanism of Action

EDTA

Purple/Lavender

Hematology (CBC)

Chelates calcium to prevent clotting

Heparin

Green

Biochemistry

Enhances antithrombin III to inhibit clotting factors

Sodium Citrate

Blue

Coagulation Studies

Binds calcium to prevent clot formation

Fluoride Oxalate

Gray

Glucose Testing

Inhibits glycolysis and binds calcium

EDTA

EDTA keeps blood from clotting by grabbing calcium ions. Calcium is needed for the coagulation process. When EDTA binds calcium, blood stays liquid. EDTA is best for hematology tests like complete blood count and blood smears. It keeps blood cells in good shape and helps you get correct results. EDTA comes in purple or lavender tubes. Always fill the tube all the way and mix it gently to stop problems.

  • EDTA works well for:

    • Hematology tests like CBC and blood smears

    • Molecular biology and genetic testing

    • Automated hematology analyzers

Tip:
EDTA tubes help keep blood samples good for checking cells.


Citrate

Citrate stops blood from clotting by binding calcium ions. This blocks the coagulation process and keeps blood from forming clots. You can reverse this effect by adding calcium back if needed. Citrate is the main anticoagulant for coagulation studies like Prothrombin Time and Activated Partial Thromboplastin Time. Citrate is found in blue-top tubes. Always fill citrate tubes to the right level for correct test results.

  • Citrate is used for:

    • Coagulation studies like PT and APTT

    • Thrombin generation tests


Heparin

Heparin stops clotting by blocking thrombin and other clotting factors. This keeps blood liquid and ready for testing. Heparin is used in green-top tubes, mostly for plasma biochemistry tests. Heparin does not make blood cells shrink, so it is good for tests that need whole cells. Heparin works with automated lab machines, including blood collection machines and infusion connector machines.

  • Heparin is good for:

    • Biochemistry tests

    • Immunology and some hematology tests

    • Doing many tests from one blood sample

Note:
Lingwen Intelligent’s blood collection machines mix the right anticoagulant with blood fast and correctly. This helps you get good results and collect high-quality plasma.


Preventing Clotting

Proper Mixing

You need to mix blood with the additive right away. This stops clots from forming in your sample. It also helps you get the right coagulation results. If you wait too long, clots can form. If you shake the tube too hard, blood cells can break. Broken cells or small clots can ruin your laboratory tube collection. Your plasma may not work for testing if this happens.

To mix blood and anticoagulant the right way, do these steps:

  1. Turn the tube upside down 5 to 10 times after you collect blood.

  2. Do not shake the tube or move your wrist quickly.

  3. Use a rotator mixer in busy labs to mix tubes evenly.

  4. Put a label on each tube before you collect blood.

  5. Turn each tube right away if you take more than one sample.

Lingwen Intelligent’s automated blood collection machines help you mix tubes the same way every time. These machines turn the tubes gently. This keeps blood and anticoagulant mixed well. Your plasma stays safe, and your blood coagulation tests are correct.

Tip:
Always collect tubes in the right order. This stops different additives from mixing. It also keeps your blood coagulation results right.


Blood-to-Anticoagulant Ratio

You must fill each tube to the right amount. The blood-to-anticoagulant ratio is very important for good coagulation tests. If you put in too much or too little blood, your blood coagulation results can change. Too much anticoagulant makes coagulation times look longer. Too little lets clots start, which uses up factors and lowers plasma quality.

Here is a table with the best ways to stop clotting when you collect blood:
