Serum-separating tubes, also known as serum separator tubes or SSTs, are used in medical clinical chemistry tests requiring blood serum.
What is the difference between a red top tube and an SST tube?
Serum Separator Tube (SST): This grey and red speckled tube (“tiger top”) is used primarily for Chemistry and Viral antibody testing. No anticoagulant is contained in the tube. Red Top Tube (Plain Non-Barrier): This tube is used for certain Blood Bank testing which requires a patient’s serum, primarily RPR testing.
What is SST tube for blood collection?
Serum Separator Tube (SST®) for serum determinations in chemistry and serology. Contains separator gel and should not be used for toxicology or drug testing. Inversions ensure mixing of clot activator with blood. Blood clotting time 30 minutes.
How long does SST tube last?
After proper centrifugation, serum can be left in contact with the gel barrier of SST tubes for up to 5 days with proper storage.
What is a PST tube?
BD Vacutainer® PST™ Tubes contain spray-coated lithium heparin and a gel for plasma separation. They are used for plasma determinations in chemistry.
What is the SST?
SST stands for Social Studies in the Indian educational system. Geography, history, and political science are only a few of the social science and humanities subjects.
What are ACD blood tubes used for?
Yellow-top tube (ACD)
This tube contains ACD, which is used for the collection of whole blood for special tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
How many times do you invert a SST tube?
volume of blood should fill the tube to the line indicated on the vacutainer label. Mix. Immediately after collection, before clotting can occur, gently mix the blood collection tube by inverting 8-10 times.
What tube is used for chemistry?
Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents.
What is a yellow SST blood test for?
Notes. The short Synacthen test is a test of adrenal insufficiency which can be used as a screening procedure in the non-critically ill patient. The test is based on the measurement of serum cortisol before and after an injection of synthetic ACTH (also known as tetracosactrin).
What color tube is for BMP?
Processing Instructions: Plasma is preferred specimen type. Green Tube/Plasma: Centrifuge after collection. Gold Tube/Serum: Allow blood to clot for 30 minutes in a vertical position and centrifuge within 2 hours.
What is an SST vacutainer?
Product description: BD Vacutainer® SST™ tubes contain spray-coated silica to aid in clotting and a polymer gel for serum separation. Samples processed in these tubes are used for serum determinations in chemistry, blood donor screening and infectious disease testing.
What is a PST lab?
A PST specialist, or patient services technician specialist, typically works in a lab and has similar job duties as a phlebotomist. In this role, you collect samples from patients, such as blood or urine, and process and store the specimens according to proper handling procedures.
What is a major cause of specimen rejection?
• Specimen condition is unsuitable for analysis. Examples: -Insufficient volume to perform tests requested. -Collected in wrong container (incorrect anticoagulant or preservative) -Improper handling, such as storage temperature or fixative.
How long can blood sit before spinning?
Serum (needs clot time)
Let the blood sit for 30 minutes to one hour at room temperature to clot before spinning and separating. A delay in centrifugation may have a detrimental effect on the sample quality and may result inaccurate results. Avoid hemolysis.
