Clinical System Name
Disseminated Intravascular Coag Panel
Synonyms
LAB2314
DIC
Coag group
DIC Diagnostic panel
DIC screen
Disseminated Intravascular coag panel
Sample Requirements
Specimen: Whole Blood
Container(s): Lt Blue/Citrate
Required Vol: one 1.8 mL tube or one 2.7 mL tube (do NOT over or under fill)
Minimum Vol: N
Note: Test includes Protime, PTT, Fibrinogen, and D-Dimer. If other blood tests are being drawn at the same time, draw citrate tubes first (following the prime tube).
Preferred method of collection is venipuncture with vacuum fill. Test results are affected by incorrect blood volume. Use of a Vascular Access Device for the collection of coag testing is not recommended.
If this method is used it requires a 5 cc clearing volume; 3 cc for size 2 French catheter or smaller. Blood must be transferred to the Lt Blue/Citrate tube by use of a blood transfer device to ensure proper fill.
Specimen should be centrifuged within 1 hour of collection.
Processing Instructions
Main Campus CPA: Core Technologist will process specimen. Deliver blood directly to Core Coag bench.
Reject due to: Clotted, Insufficient quantity (underfill), or Improper collection (overfill).
Spin: Y
Aliquot: Y
Storage location: Core 14 Freezer ( -70 C).
Core Technologist: Specimen should be centrifuged within 1 hour of collection. Spin whole blood, remove plasma. Transfer upper 3/4 layer of plasma to plastic tube affixed with large computer label.
Off-site collection: Preferred method of collection is venipuncture with vacuum fill. Test results are affected by incorrect blood volume, note the fill line on the tube. Use of a Vascular Access Device for the collection of coag testing is not recommended. If this method is used it requires a 5 mL waste volume; 3 mL for size 2 French catheter or smaller. Blood must be transferred to the Lt Blue/Citrate tube by use of the blood transfer device.
Specimen should be centrifuged within 1 hour of collection. Double spin, transfer upper 3/4 layer of plasma to plastic tube affixed with large computer label. Freeze until solid one aliquot of 1.0 mL plasma in plastic tube at -70C (preferred) or -20C.
Non-Children's Hospital Off-site collection: Ship completely frozen on dry ice.
Children's Regional Clinics: Ship completely frozen in frozen Nalgene Labtop cooler with ice pack inside an insulated soft cooler.

Methodology
Method: Clot based / immuno-turbidimetric by STA-R MAX
Analytical Volume: 1 mL plasma
Test includes Protime, PTT, Fibrinogen, and D-Dimer.
Limitations: Results affected by moderate lipemia, moderate hemolysis, and moderate icterus.
Method is affected by improper collection, processing, and storage.
High hematocrit greater than or equal to 56% requires a citrate adjusted tube.
Reference Range
Refer to individual tests for reference ranges.
Critical Values

Description
This panel includes: PT, PTT, Fibrinogen, and D-Dimer to identify patients with DIC. This particular test is used in conjunction with other tests.
