What is Blood Tube

What is Blood?

Blood collection bag with tubing. — The source image has no readable label. The product identity and use require review.

Blood is a fluid that supplies oxygen and nutrients to the cells while removing carbon dioxide and other waste materials.

Technically, blood is a transport liquid that the heart (or a comparable structure) pumps to all regions of the body before returning to the heart to restart the process.

So, what is blood collection tubes?

Blood collection tubes are sterile, vacuum-sealed containers that collect blood samples for diagnostic reasons. They are part of the Evacuated Tube System (ETS), which is intended to expedite the process of collecting blood sample.

Blood collection tubes with printed additive and volume labels. — Labels include gel tube, clot activator, vacuum tube, K3 EDTA, sodium citrate, volumes, CE, and sterile marks. Verify all labels.

Key Features

Vacuum Seal

The tubes contain a premeasured amount of vacuum that draws blood into the tube from the patient’s vein.

Additives

Some tubes contain additives to preserve or stabilize the blood sample before testing. The color of the top of the tube indicates the additives it contains.

Safety

Some tubes have safety-engineered stoppers.

Compatibility

The tubes use a standardized plastic mold that phlebotomists are familiar with.

Tube Cap Color

Most blood collection tubes contain an additive that either promotes or stops blood clotting (clot activator, anticoagulant). These are the types of cap color and what they do.

BD Vacutainer tube. — The visible label includes BD Vacutainer and 3.2%. Verify the tube type and use.

Light-Blue

Additive : 3.2% Sodium Citrate

Function : Prevents blood from clotting by binding calcium

Lab Test : Coagulation

Red-cap blood collection tube. — The visible label includes no additive, IVD, CE, and sterile marks. Verify these claims.

Red or Gold

Additive : Serum tube with or without clot activator or gel

Function : Clot activator promotes blood clotting with glass or silica particles. Gel separates serum from cells

Lab Test : Chemistry, Serology, Immunology

Blood collection tube with a printed label. — The label is not readable. Do not infer the additive or specimen use from the cap color.

Green

Additive : Sodium or lithium heparin with or without gel

Function : Prevents clotting by inhibiting thrombin and thromboplastin

Lab Test : Stat and routine chemistry

Lavendar or Pink

Additive : Potassium EDTA

Function : Prevents clotting by binding calcium

Lab Test : Hematology and blood bank

BD Vacutainer tube labeled sodium fluoride. — The visible label includes BD Vacutainer and sodium fluoride. Verify the tube type and use.

Gray

Additive : Sodium fluoride, and sodium or potassium oxalate

Function : Fluoride inhibits glycolysis, and oxalate prevents clotting by precipitating calcium.

Lab Test : Glucose (especially when testing will be delayed), blood alcohol, lactic acid
