Is a 24-year-old female, gravida 1, para 0 (G1P0), at 11 weeks gestation, with proteinuria (1+), hematuria (trace blood), ketonuria, and elevated urobilinogen (2+), concerning?

From the Guidelines

The findings on this 24-year-old pregnant woman's urine dipstick are not immediately concerning and likely represent normal physiological changes of pregnancy. The 1+ protein and trace blood can be seen in normal pregnancy due to increased glomerular filtration rate and renal blood flow 1. Ketones may indicate inadequate caloric intake or morning sickness (hyperemesis gravidarum) 1. Urobilinogen at 2+ is mildly elevated but can occur with normal pregnancy changes. The next step should be to:

• Repeat the urinalysis and obtain a urine culture to rule out urinary tract infection
• Check blood pressure to ensure there is no hypertension that could indicate preeclampsia, though this would be unusual at 11 weeks 1
• Complete blood count and comprehensive metabolic panel would be appropriate to assess renal function and rule out hemolysis 1 The patient should be counseled on:
• Adequate hydration and nutrition, with small frequent meals if experiencing nausea
• If ketones persist, nutritional counseling may be beneficial
• If protein increases to 2+ or greater, or if hypertension develops, further evaluation for preeclampsia would be warranted, though this diagnosis would be atypical before 20 weeks gestation 1 These findings should be documented as baseline values for comparison at future prenatal visits. It is also important to note that the latest guidelines recommend using multivariable models for preeclampsia risk prediction, which may include biomarkers and ultrasonography in addition to clinical risk markers in early pregnancy 1.

From the Research

Urine Dipstick Findings

• The patient's urine dipstick results show 1+ protein, trace blood, ketones present, and urobilinogen 2+ 2.
• The presence of 1+ protein in the urine dipstick may indicate proteinuria, but it is not a reliable method for diagnosing proteinuria during pregnancy 2.
• A spot urine protein-to-creatinine ratio is a more reasonable "rule-out" test for proteinuria, and a 24-hour urine collection is the reference standard for measuring urinary protein excretion 2, 3.

Clinical Significance

• The classic cutoff for defining proteinuria during pregnancy is a value of >300 mg/24 hours or a urine protein-to-creatinine ratio of at least 0.3 2.
• However, the management of gestational hypertension and preeclampsia without severe features is almost identical, and the separation into two disorders may be unnecessary 2.
• The presence of ketones in the urine may indicate dehydration or other metabolic issues, and further evaluation is necessary 2.

Next Steps

• A spot urine protein-to-creatinine ratio or a 24-hour urine collection should be performed to confirm the presence and severity of proteinuria 2, 3.
• The patient's blood pressure and other vital signs should be closely monitored, and further evaluation should be performed to rule out other potential causes of proteinuria and ketones in the urine 2, 4, 5, 6.
• The patient's symptoms and medical history should be thoroughly evaluated to determine the best course of action and to rule out any potential complications 2, 3, 4, 5, 6.
