Test Code TEG6S TEG 6S INTRA-OPERATIVE

Important Note

The TEG 6S assay is FDA approved for testing in adults for the indications of cardiovascular surgery and cardiology procedures.

Specimen Type

Whole Blood

Container/Tube

2 light blue top tubes, 3.2% sodium citrate, PROPERLY
FILLED TO THE
FILL LINE.

 

Offsite Collection Instructions

For samples drawn by venipuncture (with 21G or larger bore
needle) discard the first 3mL of blood using another blue top
tube.
Once a second blue top tube is completely filled, gently invert
the
sample tube at least five times to ensure complete mixing of
the
contents. Specimen must reach laboratory within 2 hours of
blood
collection.

Turnaround Time

2 hours

Test Includes

The package includes: TEG Kaolin (R
Time, K Time, Angle and
MA),
Rapid TEG (MA), TEG Kaolin Heparinase (R Time) and TEG
Functional
Fibrinogen (MA and fibrinogen level).

Preferred Volume

1 light blue top tube

UCMC Collection Instructions

For samples drawn by venipuncture (with 21G or larger bore
needle) discard the first 3mL of blood using another blue top
tube.
Once a second blue top tube is completely filled, gently invert
the
sample tube at least five times to ensure complete mixing of
the
contents.

Whole blood samples that are obtained from an indwelling
catheter should be collected after sufficient discard
(approximately 5 mL) has been drawn to clear the line. Ensure
indwelling catheter if free of clots. Alternatively, use an
approved Venous Arterial blood Management Protection (VAMP)
system
for blood recycling. Transfer blood to the blood collection
tube
immediately after collection. Gently invert the sample tube at
least five times to ensure complete mixing of the contents.

 

For TEG 6S OR and non-OR orders, pack
appropriately and send specimen
to
Coagulation Lab via pneumatic tube system (station 904) without
delay.

Additional Information

All 3.2% sodium citrate light blue top tubes require a ratio
of
9 parts blood to 1 part anticoagulant (example: a 3.0 mL tube
requires 2.7 mL blood added to 0.3 mL of anticoagulant).

 

Please document any drugs affecting hemostasis as well as
any
recent transfusions/fluid resuscitations in the relevant parts
of
this order in EPIC.

 

TEG6S assays will be visible in Citrix (TEG Manager) without
pathologist interpretation.  If pathology consultation is
desired, please page 3596.
