ORDERING INFORMATION: | Geisinger Epic Procedure Code: LAB2173 Geisinger Epic ID: 18327 |
Specimen type: | Platelet-free plasma |
Preferred collection container: | 2.7 mL blue-top (3.2% sodium citrate) tube |
Alternate Collection Container: | Other size blue-top (3.2% sodium citrate) tubes (e.g., 1.8 mL, 4.5 mL) |
If the patient's hematocrit exceeds 55%, the volume of citrate in the collection tube must be adjusted. Refer to Coagulation Collection Procedures for directions.
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. 1 Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio. 2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood.
Gross hemolysis; clotted specimen; specimen thawed in transit; improper labeling
The Innovance® D-dimer assay is intended for use in conjunction with a nonhigh clinical pretest probability (PTP) assessment model to exclude deep vein thrombosis (DVT) and pulmonary embolism (PE). 6 This test can be used to exclude VTE with nonhigh pretest probability (ie, low or low/moderate pretest probability).
Results of this test should always be interpreted in conjunction with the patient's medical history, clinical presentation, and other findings. DVT clinical diagnosis should not be based on the result of Innovance® D-dimer alone.
Coagulation activation results in the cleavage of fibrinogen to fibrin monomer. 7,8 The fibrin monomers spontaneously aggregate to fibrin and are cross-linked by factor XIII; this produces a fibrin clot.
R79.1 is a billable diagnosis code used to specify a medical diagnosis of abnormal coagulation profile. The code R79.1 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.#N#The ICD-10-CM code R79.1 might also be used to specify conditions or terms like clotting time above reference range, coag./bleeding tests abnormal, d-dimer above reference range, deviation of international normalized ratio from target range, extrinsic coagulation pathway finding , hormone replacement therapy bleed pattern - abnormal, etc.
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code R79.1:
Type 1 Excludes. A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!". An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note.
An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. coagulation defects D68.
Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs. White blood cells (WBC) fight infection and are part of your immune system. Platelets help blood to clot when you have a cut or wound. Bone marrow, the spongy material inside your bones, makes new blood cells.
White blood cells (WBC) fight infection and are part of your immune system. Platelets help blood to clot when you have a cut or wound. Bone marrow, the spongy material inside your bones, makes new blood cells. Blood cells constantly die and your body makes new ones.
Red blood cells live about 120 days, and platelets live about 6 days. Some white blood cells live less than a day, but others live much longer. There are four blood types: A, B, AB, or O. Also, blood is either Rh-positive or Rh-negative. So if you have type A blood, it's either A positive or A negative.
