Pregnancy, Hyperemesis Gravidarum Workup
- Author: Susan Renee Wilcox, MD; Chief Editor: Pamela L Dyne, MD more...
Laboratory Studies
- Obtain electrolyte, BUN and creatinine, and serum ketone levels.
- Measure urine gravity and ketones.
- Perform liver function tests (LFTs) if hepatitis is a concern. Of note, LFTs can be slightly elevated with hyperemesis gravidarum.
- Perform a complete blood count and urinalysis to rule out other causes, with particular concern for pyelonephritis.
- Hyperthyroidism causing nausea and vomiting is rare, a T3 and T4 level should be drawn if this is a concern. (Thyroid-stimulating hormone [TSH] can be suppressed in hyperemesis gravidarum.)
- Obtain serum amylase-to-creatinine ratio if pancreatitis is a concern.
- Serum hCG levels are not clinically useful in a patient with a known intrauterine pregnancy (IUP) and hyperemesis.
Imaging Studies
- The patient should have an ultrasonographic evaluation of her pregnancy to look for molar pregnancy or multiple gestations.
