FIBRINOGEN (FIBRINOGEN-C) – ADVANCE/FUTURATM
PRINCIPLE
Instrumentation Laboratory’s ACL ADVANCE/FUTURA are fully automated random-access analyzers for use
in coagulation testing. The principle of turbidimetric (coagulometric) clot detection is used to measure and
record the amount of time required for a plasma specimen to clot. This technique assesses coagulation endpoint
by measuring change in optical density.
The Fibrinogen-C test , based on the Clauss method, uses an excess of thrombin to convert fibrinogen to fibrin
in diluted plasma. At high thrombin and low fibrinogen concentration, the rate of reaction is a function of
fibrinogen concentration.
Fibrinogen (Factor I), a phase-reactive protein, is converted to fibrin by the action of thrombin (Factor IIa).
Several congenital abnormalities of fibrinogen result in impaired conversion of fibrinogen to fibrin during blood
coagulation. Fibrinogen is also a useful marker in the evaluation of several disease states including
Disseminated Intravascular Coagulation(DIC), liver disease, inflammatory diseases and malignancies. High
levels of fibrinogen are associated with an increased risk for cardiovascular disease. Increased levels are also
found during pregnancy and oral contraceptive use, while reduced levels are found during DIC, liver disease
and thrombolytic therapy.

QUALITY CONTROL
The ADVANCE is the primary coagulation instrument. Controls are run at the beginning of each 8-hour shift
and when new reagents are placed on the instrument. (Refer to QUALITY CONTROL, Miscellaneous Manual,
for complete details.) Modified Westgard Rules are utilized to determine if controls are acceptable and satisfy
all selected rules.
The ACL FUTURA is the backup analyzer for the ACL ADVANCE for routine coagulation tests.
Comparative analysis between the ACL ADVANCE and FUTURA allows the following differences between
the patient results of the two instruments: Fibrinogen < 15%. Comparative analysis is performed every 6
months.

Visible hemolysis may indicate possible clotting factor activation and should not be tested.
1.
Grossly lipemic specimens may cause the Advance or FuturaTM to fail. Airfuge lipemic samples.
Rerun. Include @CLAR comment (refer to SPECIMEN HANDLING FOR COAGULATION).
Note: It may be necessary to request that the patient be redrawn for 2 coag tubes to get sufficient
volume
of plasma for airfuging.
3.
Fibrinogen-C results are not affected by heparin up to 1.0 U/ml, triglycerides up to 1022 mg/dl or bilirubin
up to 19.6 mg/dl. Fibrinogen-C results may be affected by degradation products(fibrin or fibrinogen) in the
plasma assayed.
PROCEDURAL NOTES

3.
Minimum volume requirement is 0.5 ml. USE ONLY 2.0-ml SAMPLE CUPS. Do not use microcups.
The sensors do not sense the microcups properly, and the probe may crash. Damaged or misaligned
probes necessitate a service call.
1.
Critical Values: Call all critical values as soon as they have been confirmed on repeat analysis, and
document in the LIS. Press CTRL C to enter the Call screen.
4.
After the specimens have been bar coded, or manually programmed, the ADVANCE/FUTURA receives
the LIS order and then displays the tests with a “?” in the TEST REQUESTED field of the main screen.
If no communication occurs between the instrument and LIS, only the default test appears on the test
screen. In this case, the operator must check the LIS pending list (Template CoagA), and manually
enter the required tests using the Insert key. If no tests are manually entered, only the PT runs as the
default test.
3.
The LIS assigns:
a.
“16” at the end of all accession numbers for the primary draw tubes for Coagulation.
b.
“B1” for the hepadsorb aliquot labels--are not recognized for pending tests by the instruments.
Therefore, it is necessary to check the LIS for tests ordered every time a hepadsorbed specimen
is run. Do not change the “B1” ending in the instrument. UCHC records must indicate that the
specimen was run hepadsorbed, when ordered as such. The hepadsorb procedure will remove all
heparin from plasma, whether the heparin was given to the patient therapeutically, or is from a
contaminated line draw (see HEPADSORB procedure for further details.)
4.
The ADVANCE/FUTURA automatically uploads results to the LIS at one-minute intervals. Results
flagged with “^” have been uploaded to the LIS. Results flagged with “+” have not yet been uploaded
to the LIS.
5.
Internal Comments: Any time a specimen is rechecked by repeat analysis, applicator sticks, document
this action as follows:
a.
With the cursor highlighting test of interest, press the backslash (\) key to open the pop-up
window.
b.
Begin typing with a question mark (?) followed by the comment. The question mark prevents
the comment from appearing on the final report, and is therefore used for internal laboratory
comments only.
