What do doctors check for in routine blood tests?
Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working.
Diagnose diseases and conditions such as cancer, HIV/AIDS, diabetes, anemia (uh-NEE-me-eh), and coronary heart disease..
How much serum is in a SST tube?
Collection Tubes for Blood SpecimensGold or Red-Gray Marble Stopper (two-types) – SST, Serum Separator TubeAdditive:Polymer gel and powdered glass clot activatorSpecimen Type:SerumDraw Amount:5.0 mL/8.5 mLInversions:53 more rows
How much EDTA is in a tube?
A. The nominal EDTA concentration is 1.8mg EDTA per milliliter of blood.
What tube is used for drug testing?
The larger 6 mL tube is used for blood bank procedures. This tube has no anticoagulant and is used for many chemistry tests, drug levels, and blood bank procedures. There are two general types – one with K2 EDTA and one with no anticoagulant. This tube is used primarily for trace metal analysis.
How long do you spin SST tubes?
When using a serum separator tube, follow these instructions:Perform venipuncture as with any other blood collection device.Invert the tube gently no more than eight times. … Do not remove the stopper at any time. … Centrifuge for at least 15 minutes at 2200-2500 RPM within one hour of collection.More items…
How do you use SST tube?
When using a serum separator tube, collect the specimen using standard venipuncture technique. Gently invert the tube five (5) times to mix the clot activator with the blood. Avoid vigorous agitation of collected specimens. Allow the tube to clot for 20-30 minutes in a vertical position.
What is a PST tube used for?
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 a gold SST blood test for?
Specimen required: 5ml serum SST (Gold top) Tests are performed by the immunology department at St Richards Hospital. This combined test will detect auto antibodies to gastric parietal cells; mitochondria; smooth muscle and liver-kidney microsomes.
What is the yellow top blood test for?
The tests each bottle is used for are the same: the purple one is for cell count, the yellow one is for electrolytes, albumin and LDH, the grey one is for glucose, and blood culture bottles can be used for fluid cultures.

How long is blood good for in a tube?
Whole blood samples should not remain at room temperature longer than 8 hours. If assays are not completed within 8 hours, samples should be stored at +2°C to +8°C no longer than 7 days. If assays are not completed within 7 days, or the sample is to be stored beyond 7 days, samples should be frozen at -15°C to -20°C.
Why does blood clot in tube?
The top three causes of clotted samples are: 1. Leaving blood in a syringe too long before placing in tubes- syringes have no anticoagulant in them. When blood is drawn from a vein or a line, coagulation begins almost immediately.
How long does an SST tube take to clot?
30 to 60 minutesGently invert the gel-barrier tube five times to mix the clot activator and blood. Place the collection tube in the upright position in the rack, and allow the blood to clot at room temperature for 30 to 60 minutes. (Minimum clotting time is 30 minutes for patients with an intact clotting process.)
What does an SST tube contain?
Gold-top serum separator tube (SST) This tube contains a clot activator and serum gel separator – used for various chemistry, serology, and immunology tests. If the specimen requirement for a test is red-top tube(s), do not use gold-top/SST tube(s).
What is the gel in SST tube?
SST tubes contain spray-coated silica and a polymer gel for serum separation. They use for serum determinations in chemistry, serology, immunology and HIV tests . Serum separator gel that is located at end of the tube plays the role of a stable chemical and physical barrier between serum and blood clot .
Can SST tubes be frozen?
SST refers to the Serum Separator Tube containing clot activator and serum separator gel. … It is not recommended to freeze the sample in the primary blood collection tube, on the gel barrier. The gel may separate when it is frozen and thawed, resulting in red cell contamination of the sample.
