What are vacutainer tubes?

Posted on August 30, 2023 by AntiTeckAntiTeck


Vacutainer tubes are sterile tubes with a rubber stopper. They are used in the medical field to collect blood samples from patients.

A vacutainer tube is a small, plastic container that holds blood or other bodily fluid samples for testing. The container has two sections: one end has a rubber seal and a plug; the other end has a metal needle that penetrates through the seal when you pull it off. Vacutainer tubes can be used to collect blood, urine, saliva or tissue samples. Most doctors use them because they have special markings printed on them so you know how much blood to take out at once (like 4ml). The size of sample taken is based on what kind of test needs to be run (such as anemia).

What are vacutainer tubes?

Vacutainer tubes are a popular way to collect blood samples. These tubes use a vacuum to collect blood samples and are used in hospitals, clinics and doctors offices. They can also be used in research labs to take samples of bodily fluids or tissues for analysis by doctors and scientists.

Vacutainers have the advantage of being easy to use because they do not require any specialized training on how best to draw blood from patients' veins. Because they don't require any special equipment beyond what you already have at home (such as needles), vacutainers make it possible for anyone who wants their blood taken out without having any problems with bleeding or bruising afterwards!


How is a vacutainer tube used to collect blood samples?

A vacutainer tube is a medical device used to collect bodily fluids. This includes blood, urine and saliva samples.

Vacutainers are available in different sizes and can be used for adult or pediatric patients.

Blood can be collected from a vein using either one of two methods: venipuncture (the traditional method) or vacuum/aspiration (vacuum-assisted). Vacuum/aspiration allows for faster collection with less pain than venipuncture because it involves less pressure on the vein and does not require that you insert anything into your body--you only need to put your finger over the opening at one end of the tube so that it remains closed during use!

Color guide vacutainer tubes


The following is a list of common blood collection tubes, with their color and description:

  • Red Vacutainer - This tube is used for collecting whole blood. It has an anticoagulant added to prevent clotting.
  • Yellow Vacutainer - This tube contains serum or plasma instead of red blood cells (RBCs). They also have an anticoagulant added to prevent clotting, but not as much as the red vacutainer.
  • Green Vacutainer - The green top tube comes in two types: EDTA and Heparin/Lithium heparin (LiHeparin). EDTA stands for Ethylenediamine tetraacetic acid while LiHeparin is a form of heparin that can be used on patients who are allergic to regular heparin products because they contain less clumping agents than other forms do; therefore decreasing chances of complications during testing such as false negatives due to clumping issues inside test tubes resulting from improper handling procedures by technicians working at labs where these tests were performed improperly without proper training beforehand!

What is a vacutainer tube used for?


Vacutainer tubes are used to collect blood samples, urine samples, saliva samples and other bodily fluids. A needle is attached to one end of the tube by a connector that's usually made of rubber or plastic. The other end has an opening that allows you to insert it into a vein or other body part.

If you're collecting a blood sample from yourself or someone else who has an IV line in their arm (intravenous), you can use a vacutainer tube with no needle attached at all--just attach it directly onto the catheter tip using either tape or another type of fastener device called an adhesive bandage patch (also known as Tegaderm).

What types of vacutainer tubes are there?

  • SST tubes: These are the most commonly used tubes. They can be used with any blood sample and are ideal for most routine tests.
  • EDTA vacutainer: These tubes are often used when a patient has high calcium levels in their blood, such as those who have kidney failure or other conditions that cause high calcium levels in the body's fluids.
  • Heparinized vacutainer: This type of tube has been pre-treated with heparin, which helps keep clotting at bay while you're collecting your sample. It's also good if you need to use an anticoagulant like EDTA on top of this tube because it won't interfere with anything else being added to it during testing (like EDTA).
  • Plain vacutainer/ACD Blood Tubes: These are used when getting a complete blood count (CBC), but aren't really necessary unless that's all you need done on your sample; otherwise, there are better options available out there!

If you're not sure which kind of tube to use, it's best to ask your doctor or nurse what type they recommend for their lab testing. They'll know what tubes are most commonly used in their office and can help you decide which one is right for your needs.

Vacutainer tubes are a popular way to collect blood samples and other bodily fluids.

Vacutainer tubes are a popular way to collect blood samples and other bodily fluids. The tube has a rubber stopper at one end, which can be removed to allow fluid to flow into the tube. A needle is then inserted through this opening so that it pokes through the rubber stopper and into your vein or artery when you draw blood.

The process of collecting a sample with this type of tube involves first drawing air out of the tube using an automated machine called an evacuated centrifuge (or just "vacuum pump"). This creates negative pressure inside the container that sucks up any liquid contents during collection--including those pesky air bubbles!

All types of vacutainer tubes use a vacuum to collect blood samples.

Vacutainer tubes are used to collect blood samples, which are then tested in a laboratory. They're also used in research and clinical trials, as well as in medical procedures like drawing blood for transfusions or surgery prep.

The main difference between types of vacutainer tubes is the size: 2 mL (microliter), 5 mL (milliliter) and 10 mL (milliliter). The smallest ones are used for small children or infants; the larger ones can hold more liquid--which makes them ideal if you're going to be collecting a lot of blood from someone who's very sick or injured because you won't have to worry about running out so quickly.

Vacutainers make it easy to take a sample of your blood for testing.

Vacutainers are a type of medical device used to collect blood samples for testing. They come in different sizes, but they're all made out of plastic and have a rubber top that seals tightly when you twist it shut. The tube itself contains a gel-like substance that helps keep your sample from clotting while you transport it back to the lab or hospital where it will be tested.

Vacutainers are used by hospitals and labs around the world because they make taking samples easy--and safe!

Where do you get vacutainer tubes?

Vacutainer tubes can be purchased from a pharmacy or hospital. They're also available online, but you should be careful with this option because some websites may sell fake or expired products.

Vacutainer tubes are also available at other locations such as nursing supply stores, medical equipment stores and veterinary clinics that specialize in equine health care


Vacutainer tubes are used for collecting blood samples. They contain a vacuum that allows for the sample to be collected without being contaminated by air or other substances in the environment.
