Question | Answer |
---|---|
rbc: hemoglobin values (g/dl) | neonate: 20 1-6 months: 13 5-8 years: 14 13-18 years: 15 highest at birth, then decrease; starts increasing at age 5 |
rbc: hematocrit value (%) | neonate: 60 1-6 months: 40 5-8 years: 42 13-18 years: 47 high as neonate, then decreases; start increasing at age 5 |
rbc: rbc (mill/mm3) | neonate: 6 1-6 months: 4 5-8 years: 5 13-18 years: 5 high as neonate, then decrease; increase at age 5 |
rbc: plts (10X3/mm3) | neonate: 450 1-6 months: 700 5-8 years: 550 13-18 years: 450 from birth starts increasing but then decreases at age 2-5 |
wbc: (10X3/mm3) | neonate: 35 1-6 months: 18 5-8 years: 15 13-18 years: 13 birth range 10-35 then decreases |
wbc: segs | neonate: 60 1-6 months: 30 5-8 years: 50 13-18 years: 60 high at birth then decreases; start increasing at age 5 |
wbc: bands | neonate: 18 1-6 months: 12 5-8 years: 11 13-18 years: 11 high at birth then decreases |
wbc: lymphs | neonate: 30 1-6 months: 70 5-8 years: 50 13-18 years: 45 low at birth then increases, at 5 start decreasing |
newborn lab values | hct >60-polycythemia hgb<15 blood loss, hemolysis, anemia |
low and high WBC | high WBC>15; attempt to fight infection low WBC<5; system overwhelmed by infection WBC to rule out bacteremia (if <10) |
lab tests for possible sepsis | cdc with diff, ua, ucx, blood cx, stool cx, csf cell count & cx, cxr |
bilirubin values (mg/dl) | total: 0-3 day: 2-10 total: 1m-adult: 0-1.5 direct, conjugated: newborns: <1.5 direct, conjugated: 1m-adult: 0-0.5 |
Coombs test | to find level of maternal antibodies in case of ABO incompatibility and RH negative mother (both leads to fetus with anemia, jaundice, hyperbilirubinemia,etc) |
total bilirubin 20 | require phototherapy |
common screening tests for newborns | congenital adrenal disease, sickle cell, HIV, hypothyroidism, PKU |
do urinalysis | when small child/infants has fever & no signs of infection |
IgG, IgM, IgA | IgG-passes to fetus via placenta at 30-32 weeks IgM-first antibody produced by infants 4 months IgA-high in breast milk; local immunity |
reason for multiple booster shots for immunization in first year of life | no or few antibodies to produce a response |
oxygen saturation <90 | clinically significant hypoxia in children |
