LESSON 7 Flashcards
A method that uses a lancet to make a small incision into the capillary bed of the skin to obtain a small volume of blood specimen
Capillary puncture or skin puncture
These are sterile, sharp instruments that are intended for one-time use only
Lancet/Incision devices
They are designed for use in making cuts in the skin for finger or heel puncture
Lancet/Incision devices
This is a type of lancet that produces a small hole in the skin by vaporizing water in the skin
Laser lancet
This eliminates the risk of sharp injury because cauterizing the skin is not necessary
Laser lancet
Two types used in capillary puncture
Finger puncture lancet
Heel puncture lancet
This container is a small plastic tube used to hold blood specimen collected in the capillary puncture
Microcollection container
Microcollection container is also known as
Microtube
It has makings on the side that show the minimum and maximum fill levels and occasionally, comes with a narrow capillary tube
Microcollection container
These are narrow bore tubes that are made of either plastic or glass.
Microhematocrit tubes and sealants
They are typically used for hematocrit determinations
Microhematocrit tubes and sealants
Microhematocrit tubes and sealants can hold ______ and filled by capillary action
50-75uL
One end is sealed with sealants made of _____or_____
Microhematocrit tubes and sealants
Clay or Plastic
These are used for blood films for hematology determinations
Microscope slides
These are used to increase the blood flow seven-fold by warning the puncture site
Warming devices
This is a special equipment used for collecting capillary blood gas (CBG) specimen, which contains CBG collection tubes, stirrers magnet, and plastic caps
Capillary blood gas (CBG) equipment
A mixture of different blood and fluids which include these:
Capillary blood specimen
Arterial blood
Venous blood
Capillary blood
Interstitial fluid
Intracellular fluid
The bright red blood found in the pulmonary vein, left chamber of the heart, and the arteries
Arterial blood
It is the oxygenated blood in the circulatory system
Arterial blood
The blood that travels from the peripheral veins passing the venous system then through the right chamber of the heart
Venous blood
This is dark red in color because it is deoxygenated
Venous blood
Is preferred specimen for infants, young children , elderly patients, and patients with severe burns
Capillary blood
It is extracted from the venules and arterioles found in the capillary bed
Capillary blood
Fills the spaces around the cells
Interstitial fluid
Facilitates the movement of fluid in the membrane and blocks the entrance of unwanted materials
Intracellular fluid
A blood test that is used to check abnormalities in the blood cells
Routine blood film/smear preparation
Used to determine if the patient has malaria, which is diagnosed by its presence in the peripheral blood smear
Thick blood smear preparation
Small drop of blood
Routine blood film/smear preparation
Large drop of blood
Thick blood smear
Thick blood smear should be air dried for at least ______ before staining
2 hours
Is recommended for infants and small children. The blood samples are collected on the same site as routine capillary puncture specimen
Capillary blood gas specimen by heel puncture
Is used to help determine any liver disorder in infants. Collected with a heel stick
Neonatal bilirubin collection
Is done as part of the routine check for infants to determine inborn disorders such as phenylketonuria, hypothyroidism, and galactosemia, and cystic fybrosis
Newborn/Neonatal screening
Is done 24-48 hours after the baby is born, in which a few drops of blood are collected through heel stick
Newborn screening blood spot collection
