What is this test?

This is a feeding-history question, not a laboratory analysis of a blood, urine, or other specimen. It records whether an infant receives breast milk, infant formula, or another source of nutrition.

Why might I need this test?

Feeding information can help clinicians interpret an infant's growth, symptoms, hydration, or laboratory results. It may also guide counseling about nutrition or possible dietary exposures.

How is the test performed?

A parent or caregiver usually answers the question, and the response is recorded in the patient's chart. No physical sample or special laboratory procedure is required.

How do I prepare for the test?

No preparation is needed. Be ready to describe what the infant is currently fed, including breast milk, formula, cereal, food, or other nutritional products.

Reference range

Adult: 10-40 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An answer other than breast milk or formula identifies an additional dietary source that may need to be considered when evaluating growth, hydration, gastrointestinal symptoms, or other clinical findings. This response does not by itself indicate a disease or abnormal laboratory result.

Short name

Infant feeding source

Frequently asked questions

Is this a blood test?
No. It is a question about the infant's feeding history and usually requires only a caregiver response.
What kinds of feeding should I report?
Report breast milk, infant formula, cereal, food, supplements, or other nutrition products given to the infant.
What does an “other” feeding response mean?
It means the infant receives at least one nutritional source besides breast milk or formula. Discuss the specific diet with a healthcare professional if it is relevant to the infant's care.
