EDTA.
sst tube contain a specific type of gel that separates the blood after centrifuge.
A blood alcohol concentration (BAC) test is typically performed using a tube called a blood collection tube, specifically designed for venipuncture. These tubes may contain additives like EDTA or sodium fluoride to preserve the blood sample. In some cases, breathalyzers are used for quick assessments of alcohol levels through breath samples, but for precise measurement, blood samples in collection tubes are preferred.
Typically, a red-top or green-top tube is used to collect blood for a digoxin level test. The blood sample is collected through a venipuncture procedure, and the tubes contain no anticoagulant. It's important to follow standard blood collection procedures and handle the sample with care to ensure accurate test results.
It contains nothing, however it is silicone coated.
Plain red top tubes do not require mixing at the time of collection. These tubes contain no additives or anticoagulants and are used for serum collection.
Sometimes the vacuum collapses the vein.
A red-top tube is typically used for the CEA (carcinoembryonic antigen) test. This tube does not contain any anticoagulants and is used for serum collection.
A blood sample is typically used for testing herpes. This sample is usually collected through a venipuncture procedure, where blood is drawn from a vein in the arm using a vacutainer tube or a similar blood collection tube. The specific type of tube may vary depending on the laboratory's requirements.
When venipuncture is performed using a lavender vacutainer tube, the sample collected is typically used for hematology testing, such as complete blood count (CBC), erythrocyte sedimentation rate (ESR), and blood typing. The lavender top tube contains EDTA as an anticoagulant to preserve the blood sample for these types of tests.
The vacuum tube method of venipuncture offers several advantages, including reduced risk of contamination, as the tubes are pre-packaged and sterile. It allows for the collection of multiple samples with a single puncture, minimizing discomfort for the patient. Additionally, the vacuum mechanism facilitates efficient blood flow, ensuring accurate and consistent sample volumes. This method also enhances safety for both the patient and the healthcare provider by reducing the need for manual blood handling.
A FBS (Fetal Bovine Serum) collection tube is used to collect blood samples from animals for various laboratory tests. These tubes contain a special coating that helps prevent clotting and preserve the serum for analysis. After collection, the blood is usually centrifuged to separate the serum for further testing.
In capillary blood collection, the microcollection tube that should be filled last is typically the tube containing an additive, such as a gel separator or anticoagulant. This helps to prevent contamination of the sample with other additives from previously filled tubes. Often, the tube for hematology tests, which does not contain additives, is filled first, followed by tubes for biochemistry or other analyses.
