What is the additive in yellow tubes

Sps

What is sps

Sodium polyanethol sulfonate, inhibits complement and phagocytosis

Common test for yellow tubes

Blood culture for microbiology

What do yellow tubes test on

Whole blood

What is the additives in light blue tubes

Sodium citrate

What does sodium citrate do

It’s an anticoagulant that preserves clotting factors

What is a common test for light blue tubes

Coagulation tests, PT,PTT, INR, D-dimer

What does the light blue tube test on

Plasma

what are the additives in red tubes

None(glass) OR silica clot activators(plastic)

addative that stimulate clotting

Clot activator

What are common test for red tubes

chemistry, serology, Blood bank

What is in gold/tiger top tubed

Serum separator gel or polymer gel

What is polymer gel/ Thixotropic gel

forms a separation barrier between serum and cells after centrifugation

What are common test done by gold/tiger tops

Tests for serum chemistry, such as lipid panel, liver function tests, and thyroid tests, do most infectious disease tests

What is SST

serum separator tube, contains a gel that separates the serum from the blood cells after centrifugation

What is in dark green tubes

sodium heparin; an anticoagulant for plasma collection or Lithium heparin

What are common dark green tube tests

Arterial blood gas (ABGs), Electrolytes, ammonia

What is in lavender tubes

EDTA, an anticoagulant used to prevent blood clotting.

What are common tests for lavender tubes

complete blood counts (CBC), ESR (Erythrocyte Sedimentation Rate)

what is EDTA

ethylenediaminetetraacetic acid; binds calcium to stop coagulation cascade

What is in gray tubes

sodium fluoride and potassium oxalate

What are common tests for Grey tubes

Glucose testing, lactate acid testing, and blood alcohol levels.

what do gray tubes test on

plasma or serum

Median cubital vein

The primary vein used for venipuncture, located in the middle of the antecubital fossa. It is preferred due to its size and accessibility.

Cephalic vein

A vein in the arm that runs along the thumb side and is often used for venipuncture.

Basilic vein

A vein located on the inner side of the arm that is generally more challenging to access but can be used for venipuncture.

agent that stop bacteria growth

Antiseptic

Hollow tube within the needle

lumen

Chemical added to evacuated tubes

to preserve or enhance the quality of the blood sample during collection or Additives

metabolic sugar breakdown in cells

glycolysis

What is Hemolysis

The breakdown of red blood cells

iatrogenic anemia

Anemia caused by excessive medical treatment or procedures

what is bacteriostatic

A solution that inhibits the growth of bacteria but does not kill them; to prevent bacterial contamination.

difference between outpatient and in patient

Outpatients receive care without being admitted to a hospital, while inpatients are admitted for at least one night for treatment.

what is heparin

an anticoagulant used to prevent the formation of blood clots by inhibiting thrombin and factor Xa in the coagulation pathway.

difference between sodium heparin and lithium heparin

Sodium heparin is used for blood tests and as an anticoagulant, while lithium heparin is often used in specific tests requiring minimal interference.

what is Inversion and how many times should it occur

gentle mixing blood collection tubes for proper mixing of the anticoagulant with the blood sample: 5-10 times depending on the tube type.

What is PST

Plasma Separator Tube, which contains gel and anticoagulant to separate plasma from blood cells during centrifugation.

relationship between needle luman and gauge

inverse; as the gauge number increases, the needle's lumen diameter decreases. This means larger gauge needles have thinner walls and smaller openings.

Luer adaptor

allows secure connection between a syringe and a tube or needlesmooth transfer of fluids.

antiseptic vs disinfectant

Antiseptics reduce the risk of infection on living tissues, disinfectants are used to destroy bacteria and viruses on inanimate surfaces.

16-18 inch Guage

used for blood bank/ donation

difference between red glass tubes and red plastic tubes

Red glass tubes are used for serum collection and dont contain additives, while red plastic tubes contain a clot activator, allowing for quicker clot formation.

thrombin

A blood-clotting agent used in laboratory settings, often found in clot activator tubes.

difference between anticoagulants and clot activators

Anticoagulants inhibit blood clotting, while clot activators promote coagulation for quicker serum separation.

what do red tube test on

Serum

what gold/tiger tubes test on

serum

what do green tubes test on

plasma

what do lavender tubes test on

whole blood

difference between whole blood, plasma, and serum

Whole blood has all components of blood, plasma is the liquid portion after centrifugation without clotting, and serum is the liquid left after coagulation has occurred.
