Clearly the investigations are mostly dependent upon the aetiology. Principal investigations however should include:
- full blood count
- urea and electrolytes
- clotting studies
- blood gases
- septic screen if infection is a possibility
If blood is vomited or passed in stool in the first few hours of life, then the Apt test may be helpful in distinguishing it from swallowed maternal blood.
