NUR 241: T1: prenatal
lab test fully solved &
updated 2025
hemoglobin
normal value: 12-16
pregnancy value: 10-14
performed: 1st visit for baseline
follow up: Rx iron in 2nd trimester if needed
WBC
normal value: 5,000-10,000
pregnancy value: 5,000-15,00
performed: 1st visit for baseline
follow up: normal to increase during labor
platelets
normal value: 150-450
pregnancy values: 150-350
performed: 1st visit
follow up: must be at least 100 for an epidural, if decreased may be
a sign/ symptom for HELLP
blood type and Rh
blood type to screen for maternal fetal incompatibility
performed: 1st visit to r/o sensitization
follow up: Rh- need to give immune globulin at 28 weeks.
- if there is blood mixing, 72 hrs of delivery if baby is + , give
Rhogam
, indirect coombs
pregnancy values: less than 1:8
performed: at 1st visit to rule out sensitization
follow up: monitor and intervene if increases
VDRL/ RPR
pregnancy value: negative
when performed: 1st visit and at 36 weeks to r/o syphillis
follow up: if positive need antibiotics (penicillin), repeat culture,
treat partner, retest at 36 weeks.
rubella titer
pregnancy value: greater than 1:8 = you have immunity
1:8- considered equivocal
when performed: 1st visit to see if you have immunity
follow up: if non immune teach patient to avoid people with rubella,
until they are after 20 weeks gestation.
-if non immune they will get a rubella vaccine after delivery, the day
of discharge - given at discharge to make sure they dont get a fever
and have to stay.
if baby is + at delivery, isolate for one year.
if rubella is given at the same time as rhogam we have to draw a
titer and check her titer at the first visit, like 6-8 weeks later to see
if she has an immunity. rhogam prevents antibodies from building
up and rubella is to build antibodies
1 hr glucose tolerance test (GTT)
pregnancy values: want it less than 130-140
when performed: around 24-28 weeks to rule out gestational
diabetes
follow up: if its elevated need to do a 3 hr test, if 2/3 of those levels
are elevated shes considered gestational diabetic
