What is a SST blood test for?
Your doctor has recommended that you have a short synacthen test (SST).
It is a test to check the amount of cortisol in your body and to check how well your body can produce cortisol.
What is cortisol.
Cortisol is one of the essential steroid hormones to keep you healthy..
What is the correct order of blood draw tubes?
The correct order of draw follows:Blood culture tube or bottle.Sodium citrate tube (eg, blue closure)Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)Heparin tube with or without gel (eg, dark green, light green, speckled green closures)More items…•
What tests are SST tubes used for?
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.
What is the gel in SST tube?
SST refers to the Serum Separator Tube containing clot activator and serum separator gel. PST refers to the Plasma Separator Tube containing lithium heparin and plasma separator gel.
What happens when blood is centrifuged?
A machine called a centrifuge spins your blood to separate your red blood cells, platelets and plasma. As the blood is separated, the heavier reds cells sink to the bottom and are given back to you.
What tube has a clot activator?
Red-top tube: Tube does not contain an anticoagulant. This tube is used for collecting serum or clotted whole blood specimens. Tiger-top tube (serum separator): Tube does not contain an anticoagulant but does contain a clot activator and serum separator gel. This tube is used for collecting serum.
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.
What blood tests need to be on ice?
Certain analytes must be preserved prior to analysis by keeping the specimen chilled. To ensure accurate results of such specimens, transport them in ice slurry. i.e. ACTH, Acetone, Angiostensin Converting Enzyme (ACE), Blood Ammonia, Catecholamines, Free Fatty Acids, Lactic Acid, Pyruvate, Renin Activity.
What is a gold top tube blood test?
Tube MUST be filled 100% – No exceptions! Gold Top (Serum Separator, “SST”) Contains separating gel and clot activator. 6.0 mL. Most chemistry, endocrine and serology tests, including Hepatitis and HIV.
How much serum is in a SST tube?
1.0 mL of serum is the minimum acceptable volume needed for testing.
What does SST mean in medical terms?
Serum-separating tubesSerum-separating tubes, also known as serum separator tubes or SSTs, are used in medical clinical chemistry tests requiring blood serum.
What is normal blood count?
Normal Blood Count Ranges In general, the normal range for a red blood cell count is 4.5 to 5.5 million cells/mm3 if you’re male and 4 to 5 million cells/mm3 if you’re female. For white blood cell count, the normal range is 5,000 to 10,000 cells/mm3, and for platelets, the typical range is 140,000 to 400,000/mm3.
How does cortisol affect sleep?
The stress hormone cortisol is produced by the HPA axis, which also helps coordinate your sleep cycles. When the HPA axis is disrupted through poor nutrition, chronic stress, or illness, this can result in insomnia and other sleep disturbances.
What are the signs of adrenal gland problems?
What are the symptoms of adrenal gland disorders?Upper body obesity, round face and neck, and thinning arms and legs.Skin problems, such as acne or reddish-blue streaks on the abdomen or underarm area.High blood pressure.Muscle and bone weakness.Moodiness, irritability, or depression.High blood sugars.Slow growth rates in children.
How long can blood sit before spinning?
Allow the blood to clot in an upright position for at least 30 minutes but not longer than 1 hour before centrifugation. Centrifuge for at least 15 minutes at 2200-2500 RPM within one hour of collection.
What is SST tube used for?
This tube is used primarily for trace metal analysis. Serum Separator Tube (SST®) – This tube contains a clot activator and serum gel separator. It has no anticoagulant and is used for many chemistry tests. It cannot be used for certain drug levels or any blood bank procedures.
What is the purpose of a serum separator in a blood collection tube?
Serum separator collection tubes contain a gel that separates the clot from the serum in whole blood specimens. During centrifugation, the gel moves to create a barrier between cells and serum, providing access to the serum for various chemistry, serology and other procedures.
What does low cortisol feel like?
Too little cortisol may be due to a problem in the pituitary gland or the adrenal gland (Addison’s disease). The onset of symptoms is often very gradual. Symptoms may include fatigue, dizziness (especially upon standing), weight loss, muscle weakness, mood changes and the darkening of regions of the skin.
What is a 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.
Does low cortisol cause weight gain?
Proper thyroid function helps to maintain a healthy metabolism, but both high and low cortisol levels can impair the conversion of thyroid hormone from its inactive form to its active from. This can result in a low thyroid situation, causing weight gain and symptoms of poor metabolism.
How do you prevent blood clots in a test tube?
The tubes need to be inverted at least 10 times to make sure that the anticoagulant is properly mixed with the blood components to stop the entire clotting mechanism. A slow draw into a vacutainer tube- tube should be mixed intermittently until filled to prevent hemostasis.
