Step 18: Transport Specimen to the Lab
specific sequence with
which blood must be drawn and collected in tubes to avoid cross contamination of additives between the tubes. The Order of Draw should be Blood gas specimens (CBGs), EDTA specimens, other additive specimen and serum specimen.
Order of Draw
For infants, the incision site should be less than ____________deep and to
avoid bone damage the incision the recommended site should be in the plantar surface of the heel, or on the median or lateral edge.
2.0 mm
Warming the incision site increases the blood circulation in the area for up to seven times. Using a warm washcloth or towel, warm the site for _______minutes.
3 to 5
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
is done as part of the
routine check for infants to determine inborn disorders.
Newborn/neonatal screening
used to help determine any liver disorder in infants. This is collected with a heel stick
Neonatal bilirubin collection
✓ Newborn screening blood spot collection is done ________ hours after the baby is born
24 to 48
Capillary puncture also known as___________
Skin puncture
Capillary blood is a mixture of _____________
Oxygenated and deoxygenated blood
Capillary is the _________ blood vessel
Smallest
Additive prevent ______
Coagulation
Microhematocrit tubes holds approximately__________microliters of blood
50-75 microliters
it should be sterile and sharp enough
Lancet/incision devices
Produce small hole, the main purpose is for cauterization of wartz
Laser Lancet
Mini version of tubes, made by plastic to prevent activation of platelets
Microcollection container
It has a very small hole to measure the amount of hematocrit, red cell,plasma,packed cell within a blood specimen
Microhematocrit tubes
Made up by clay, plastic ,but in laboratory they use candle/wax to form a tight leak-proof seal used during centrifugation.
Sealant
Microhematocrit tube;
Red
Heparinized
Microhematocrit tube;
Blue
Nonheparinized or plain
Primarily used for making blood smear
Microscope slide
Blood smear is also known as ________
Peripheral blood smear
Used to stimulate blood flow
Warming devices
use to collect capillary blood gas specimen and to measure blood pH
Capillary blood gas Equipment (CBG)
the composition of capillary blood specimen
- the capillary blood specimen
- arterial blood
- venous blood
4.capillary blood
color of arterial blood
bright red -oxygenated
color of venous blood
dark purple- deoxygenated
color of capillary blood
dark purple to bright red
*but it’s usually color red
Step 6: Select the Puncture/Incision Site
For infants, the incision site should be less than _________ deep and to avoid bone damage the incision the recommended site should be in
the plantar surface of the heel, or on the median or lateral edge.
2.0 mm
Step 6: Select the Puncture/Incision Site
As a general criterion, the skin of the incision site should be _______, ________, _________. The selected area should be free from
scars, cuts, bruises, rashes, cyanosis, edema, or infection.
pink,normal in color, and warm
ROUTINE AND THICK BLOOD SMEARS
______________is a blood test that is used to check abnormalities in the blood cells.
Routine blood film/smear preparation
_________is used to determine if the
patient has malaria which is diagnosed by its presence in the peripheral blood smear
Thick blood smear preparation
__________which is recommended for infants and small children. The blood samples are collected on the same site as routine capillary puncture specimens.
Capillary blood gas specimen by heel puncture
___________is used to help determine any liver disorder in infants. This is collected with a heel stick.
Neonatal bilirubin collection
________is done as part of the routine check for infants to determine inborn disorders.
Newborn/neonatal screening
is done 24 to 48 hours after the baby is born, where a few drops of blood are collected through heel stick to determine disorders
that are not apparent at birth that could lead to disability or even death.
Newborn screening blood spot collection
