NeoSpHb Study: Can a Painless Device Detect Anaemia in Babies Without Blood Tests? A Study in the Neonatal Intensive Care Unit (NICU) (NeoSpHb)

24. august 2026 opdateret af: Aliyyah Mohammad Khuzaini, University of Malaya

Validation of Non-invasive Spectrophotometric Haemoglobin (SpHb) Measurement for Detection of Anaemia and Observation of Trends in Infants Admitted to the Neonatal Intensive Care Unit (NICU): A Prospective Diagnostic Accuracy Study.

The goal of this study is to evaluate the diagnostic performance and feasibility of non-invasive spectrophotometric haemoglobin (SpHb) measurement for detecting anaemia in infants admitted to the Neonatal Intensive Care Unit (NICU). The main questions it aims to answer are:

  1. What is the agreement between non-invasive SpHb and laboratory reference total haemoglobin (tHb)?
  2. How accurately can non-invasive SpHb detect clinically significant laboratory anaemia (Hb < 10g/dL)?
  3. What is the feasibility (success rate and time-to-reading) and what physiological factors (e.g., perfusion index) moderate measurement accuracy in NICU infants? Researchers will compare non-invasive continuous SpHb readings against routine invasive laboratory haemoglobin values (tHb) obtained during standard clinical care from the same clinical encounter.

Participants will:

  1. Have a non-invasive optical sensor applied to an approved peripheral site (e.g., foot or palm) to record an SpHb reading whenever routine blood sampling is required by their attending clinician.
  2. Undergo standard routine blood sampling (venous, arterial, or capillary) for laboratory haemoglobin testing as part of usual clinical care, with no extra blood drawn for research purposes.

Detaljeret beskrivelse

What is the purpose of this study?

This study aims to find out how accurate a non-invasive device (SpHb) is in measuring haemoglobin (red blood cells) levels in babies admitted to the NICU. The study involves the use of the Masimo SpHb® (Spectrophotometric Hemoglobin), a non-invasive monitoring device currently used in clinical settings. The device is handheld and connected to a computer/tablet for recording measurements. It will be placed on the child's skin to measure the child's hemoglobin. The procedure does not involve needles, radiation, or painful interventions.

Why is this study important?

Babies in NICU often have anemia, where their red blood cells level is low. To monitor this condition, babies often need repeated blood tests, which can cause pain and blood loss. This study may help reduce unnecessary blood sampling in the future.

What type of study is this?

This is an observational study. We will compare readings from a non-invasive device with routine blood test results.

What is the procedure that is being tested? A device called Masimo SpHb® is placed on the baby's skin to measure haemoglobin using light. No blood is taken for this measurement.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: SpHb
Infants admitted to the NICU will undergo non-invasive SpHb measurement, with results compared against laboratory haemoglobin values obtained as part of routine clinical care.
Enhed: Spectrophotometry hemoglobin
  1. The index test utilizes multi-wavelength spectrophotometry (Masimo Radical-7® with rainbow® sensors) applied topically to peripheral tissue (e.g., foot, palm, or digit). It requires zero skin punctures, creates no additional iatrogenic blood loss, and causes no pain or distress to fragile neonates.
  2. Unlike standard diagnostic studies that require dedicated blood sampling for research, this protocol collects reference laboratory total haemoglobin (tHb) strictly when clinically indicated for routine care. No extra phlebotomy is performed solely for the study.
  3. Non-invasive SpHb measurements are acquired within a strict 5-minute window of routine clinical blood sampling to eliminate physiological variability over time and ensure paired accuracy assessment.
