HELLP Syndrome Misdiagnosis: When Obstetric Emergencies Are Missed

September 1, 2026

HELLP syndrome is a life-threatening obstetric complication that requires prompt recognition and urgent intervention. Despite being a well-recognized condition in obstetric medicine, HELLP syndrome is misdiagnosed or dismissed at alarming rates, sometimes with fatal consequences for the mother, the baby, or both. For families in Houston, Dallas, San Antonio, Austin, Sugar Land, The Woodlands, Katy, and across Texas who have experienced a HELLP syndrome tragedy, understanding when a missed diagnosis constitutes obstetric malpractice is essential to seeking accountability and justice.

What HELLP Syndrome Is and Why It Is Dangerous

HELLP syndrome is a severe variant of preeclampsia involving Hemolysis, Elevated Liver enzymes, and Low Platelets. It typically occurs during the third trimester of pregnancy or in the immediate postpartum period and represents a multi-system obstetric emergency. HELLP syndrome can rapidly progress from early symptoms to life-threatening complications including hepatic rupture, disseminated intravascular coagulation, placental abruption, acute renal failure, pulmonary edema, and maternal and fetal death.

The danger of HELLP syndrome is compounded by the fact that its presentation is often atypical and can mimic a range of more benign conditions. Women with HELLP syndrome frequently present with right upper quadrant or epigastric pain that is mistaken for gallbladder disease, gastritis, or acid reflux. Nausea and vomiting are common and can suggest flu or food poisoning. Malaise and headache may be attributed to viral illness. These overlapping symptoms with common, non-emergency conditions contribute to a pattern of missed and delayed diagnosis that can have fatal consequences.

The Standard of Care for HELLP Syndrome Recognition

Obstetricians, emergency physicians, and obstetric nurses are expected to maintain a high index of suspicion for HELLP syndrome in pregnant and recently postpartum women presenting with upper abdominal pain, nausea and vomiting, malaise, headache, or visual changes, particularly in combination with hypertension or signs of preeclampsia. The standard of care requires laboratory evaluation including a complete blood count with platelet count, liver function tests, and a coagulation panel when HELLP syndrome is in the differential diagnosis.

The diagnosis of HELLP syndrome is confirmed by laboratory criteria: hemolysis evidenced by abnormal peripheral blood smear or elevated bilirubin, elevated AST and ALT levels indicating hepatic involvement, and platelet count below 100,000 per microliter. A clinician who fails to order these tests in a pregnant or postpartum woman presenting with a compatible clinical picture is deviating from the standard of care.

How HELLP Misdiagnosis Causes Harm

When HELLP syndrome is missed or delayed, the window for intervention narrows rapidly. Definitive treatment of HELLP syndrome requires delivery of the fetus and placenta, which is the only way to halt the underlying pathological process. In severe cases, magnesium sulfate is administered to prevent seizures, blood pressure is aggressively controlled, and corticosteroids may be given to improve platelet counts temporarily and support fetal lung maturation in preterm cases.

Delayed diagnosis means delayed delivery and delayed treatment. In that window, the mother may develop hepatic rupture, a catastrophic complication with extremely high mortality, or progress to fulminant disseminated intravascular coagulation with uncontrollable hemorrhage. The fetus may suffer hypoxia and injury from placental compromise or premature placental abruption. Deaths that occur in this setting are not inevitable outcomes of a dangerous disease. They are often the preventable consequence of a missed diagnosis.

The Legal Elements of a HELLP Misdiagnosis Malpractice Claim

An obstetric malpractice claim based on HELLP syndrome misdiagnosis requires establishing that the treating physicians and nurses failed to recognize the signs and symptoms of HELLP syndrome that a reasonably competent obstetrician or emergency physician would have recognized, failed to order the appropriate laboratory workup to evaluate for HELLP syndrome, failed to make or communicate the correct diagnosis in a timely manner, or failed to initiate appropriate treatment including delivery once the diagnosis was made or reasonably suspected.

Causation is established by demonstrating that with timely recognition and treatment, the mother and baby would have had a materially better outcome. Expert testimony from obstetricians, maternal-fetal medicine specialists, and in cases involving fetal or neonatal injury, neonatologists and pediatric neurologists, is typically required to establish both the standard of care and causation.

Who Patients and Families Can Seek Accountability From

In HELLP syndrome misdiagnosis cases, liability may extend to the obstetrician who failed to recognize the condition or dismissed the patient’s symptoms, the emergency room physician who evaluated a pregnant patient with compatible symptoms and failed to include HELLP in the differential, the nursing staff who failed to communicate critical clinical findings to the physician, the hospital system that created conditions under which inadequate monitoring occurred, or any combination of these parties depending on the specific facts.
