Can a Finger-Prick blood test reveal hidden malaria in the placenta?
NCT ID NCT01555255
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Malaria in pregnancy can hide in the placenta and harm both mother and baby, yet it often goes undetected. This study enrolls about 1,200 pregnant women in Africa to see whether malaria rapid diagnostic tests, blood smears, and PCR on maternal blood can accurately detect or predict placental malaria. Researchers compare these tests during pregnancy and at delivery, and track birth weight and maternal hemoglobin to understand how placental malaria relates to poor outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- malaria rapid diagnostic tests, blood smears, and PCR on maternal blood
- What this could lead to
- If the tests prove accurate, clinics could screen pregnant women for placental malaria with a finger-prick blood test and start treatment sooner, which may reduce low birth weight and anemia.
- What could go wrong
- Peripheral blood tests may miss infections that stay in the placenta, so accuracy could fall short. The study measures test performance, not whether screening improves outcomes, and results may differ across transmission settings.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Specific participant selection criteria include: 1. Presenting for care after quickening and before onset of labor (i.e. in the second or third trimester of pregnancy) 2. Age between 16 years and 44 years, inclusive 3. Willingness and ability to follow up with study visits and activities through the duration of pregnancy and at delivery 4. Absence of history of serious adverse reaction to sulfa drugs 5. Absence of history of serious adverse reaction to artemisinin-based drugs (depending on national policy on treatment of malaria in pregnancy) 6. Absence of HIV infection (both because guidelines for malaria prevention in pregnancy for HIV-infected women differ from those for HIV-negative women, and in order to avoid confounding of pregnancy outcomes by HIV-related complications or treatments in this early evaluation) 7. Absence of history of or current obstetrical complications (e.g. pre-eclampsia, eclampsia, hypertension during pregnancy, post-partum hemorrhage, evidence of multiple gestation) 8. Absence of chronic disease (e.g. diabetes mellitus, sickle cell disease) 9. Absence of evidence of severe acute disease requiring inpatient management or referral 10. Provision of written informed consent 11. Enrollment Hb ≥7 g/dL
