Phlebotomy 10 Flashcards
drops of blood for testing obtained by puncture or incision in the capillary bed in the dermal layer of the skin with a lancet or sharp device
capillary specimen
disposable device that punctures the skin or makes an incision
lancets
collecting small amounts of blood by capillary puncture
microcollection
microcollection containers used to collect tiny amounts of blood obtained from capillary puncture
microtubes
disposable, narrow-bore plastic capillary tubes that hold 50-75uL of blood
microhematocrit tubes
ability of a liquid to flow into a narrow space or a thin tube without the use of external force, ie. gravity
capillary action
collected in long capillary tube with heparin; uses stirrers, magnets, and caps
capillary blood gases (CBG)
tissue fluid from spaces between cells
interstitial fluid
fluid within cells
intracellular fluid
puncturing a finger
fingerstick
bluish in color usually from shortage of oxygen in blood
cyanotic
swollen with fluid

newborns
neonates
brain dysfunction caused by toxic levels of bilirubin
kernicterus
blue light that can be used to reduce bilirubin levels and filters out damaging UVs
phototherapy
state mandated testing of newborns to detect certain genetic, metabolic, hormonal and functional disorders or conditions that can cause severe mental handicaps or other serious problems in not detected or treated early
neonatal screening (NBS)
genetic disorder characterized by a defect in the enzyme that breaks down phenylalanine, to convert into tyrosine
phenylketonuria (PKU)
disorder characterized by insufficient thyroid hormones; hinders growth and brain development
hypothyroidism
inherited disorder characterized by lack of enzyme needed to convert galactose from milk into glucose
galactosemia
disorder caused by one or more mutations in the gene that directs the protein responsible for regulating the transport of chloride ions across cell membranes; affects the lungs and pancreas causing mucus blockages
cystic fibrosis
drop of blood spread thin on a microscope slide
blood film/smear
test in which number, type, and characteristics of blood cells are determined by examining stained blood under a microscope
differential (Diff)
thinnest portion of a smear that is 1-cell-thick and where a Diff is performed
feather
