on FreezingBlue Flashcards. What would you like to do?
additive in a black stopper?
blood to anticoagulant ratio is critical in _____ stopper colored tubes, because underfilled tubes prolong clotting time and can't be accepted for testing.
light blue sodium citrate
other words for precipitating calcium
binding calcium, or chelating calcium
what additives binds calcium
- -sodium citrate/ citrates
- -potassium oxalate
what do we do if microclots are detected in a hematology specimen?
recollect because they can't be used for testing
what additive inhibits thrombin formation
what department does EDTA usually go to?
what department does sodium citrate go to?
preferred additive for potassium tests and why?
heparinized plasma is preferred over serum, because when blood clots potassium is released from the serum and can falsely elevate results.
what department does heparin go to
which tube contains antiglycolytic agents
what's the consequence of excess oxalate to blood ratio?
helolysis of the blood
the breakdown or metabolism of glucose. antiglycolitic agents (grey tubes) prevent glycolysis
sodium fluoride is the most common type of
antiglycolytic (found in grey tube)
what patients will glycolysis occur faster in?
infants and patients with leukemia
tube used to collect ethanol specimen to prevent the decrease in alcohol concentration due to glycolysis or an increase in fermentation by bacteria?
sodium fluoride in grey tube
clot activators include
silica found in glass and celite
how fast does silica cause blood to clot
15 - 30 minutes
how fast does blood clot in tubes with the additive thrombin
how fast do gold plastic tubes or mottled red/grey tubes clot and why?
5 minutes because they contain thrombin
RST stands for
rapid serum tubes
PST stands for
PPT stands for
plasma preparation tubes
common anticoagulants (p215)
- EDTA: Lavender tube
- Sodium Citrate: Red tube
- Heparin: Green tube
- Oxalate: grey tube
what tube must not be used for a lithium levels?
lithium heparin (green tube),
what can not be used to collect sodium specimens or electrolyte panels?
sodium heparin, because sodium is part of the panel
Light blue stopper contains
goes to hematology deparmtnet
- Used for:
- -(D-D1) D-Dimer
- -(DIC pahel vials) Disseminated intravascular coagulation panel
- -Factor assay
green tubes contain
sodium heparin or *lithium heparin are anticoagulants
goes to chemistry department
- Used for:
- -Plasma: (BMP) Basic Metabolic Panel
- -Plasma: (ALP) alkaline phosphate
- - Plasma: (CEA) Carcinoembryonic antigen
Green marble and mint colored tubes have ____ aditive
Lithium heparin + thixotropic gel
grey tubes contain
sodium fluoride and potassium oxilate
Goes to Chemistry department
- used for:
- Serum: (ETOH) Alcohol (blood)
- Plasma: (Lact) Lactic acid (blood lactate)
- Plasma: (FBS) Glucose, fasting
Red/black combo AKA red marble, red and gold tubes contain
Thixotropic Gel and clot activator
goes to Chemistry department
- Used for:
- -serum: cortisol, timed
- -Drug monitoring
- -Serum: Electrolytes
- -Serum: (GGT or GT) Gamma-glutamyl transpeptidase
red plastic tubes contain
red glass tubes contain
no additive. Glass is a natural clot activator
Lavender tubes contain
goes to hematology lab
- used for:
- -Antibody screen
- -blood group &Rh type
American Society for Clinical Pathology
Material safety data sheet
Personal protective equipment
Occupational Safety and Health Administration,
Centers for Disease Control
Human immunodeficiency virus
National Fire Protection Association
American Society for Clinical Laboratory Science
- routine general testing stable patients.
- -STAT- immediate
- -Timed (ten minute window)
- -ASAP: inpatient has 2 hour Turn around time (TAT) outpatient has one business day
gas exchange in the lungs
RBC's transport CO2 to the lungs where CO2 is exchanged for O2. Both are bound in the RBC to a molecule coated in Hemoglobin
iron and protein
how to check ID
- -name DOB and spell last name
Evacuated Tube System.
order of draw for dermal puncture
- blood gas specimens (CBGs)
- other anticoagulants
- red series
equipment for dermal puncture
- -mucrocollection container
- -microhematocrite tubes and sealants
location of dermal puncture on adult
- palmar surface of distal or end segment of middle or ring finger on nondominant hand.
- central, fleshy area to the side of the center perpendicular to grooves in the whorls.
clean up after other cells
phagocytes in tissue
are present during an allergic reaction
tests affected by povidone-iodine
- bilirubin, uric acid, phosphorus, & potassium
location of dermal puncture on infant
(Max depth, and preference on newborns)
