What is this test?
This is a laboratory analysis of a breast milk sample. The abbreviated code identifies a milk-related specimen, but it does not clearly specify the substance, measurement, or testing method being used.
Why might I need this test?
Breast milk testing may be ordered to evaluate a nutrient, medication or chemical exposure, contaminant, or other substance relevant to an infant or breastfeeding parent. The reason depends on the exact analyte ordered.
How is the test performed?
A laboratory professional examines the submitted milk sample using the method appropriate for the ordered analyte. Some tests require the milk to be collected or stored in a special bottle provided by the laboratory.
How do I prepare for the test?
Follow the collection and storage instructions provided with the test kit. Requirements can vary, so do not transfer milk into another container, refrigerate or freeze it, or add anything to it unless the laboratory specifically directs you to do so.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An abnormal result may reflect a nutritional difference, contamination, medication or chemical exposure, infection, or another condition, depending on what was measured. Because the analyte and method cannot be confirmed from this code, the result should be interpreted only with the full laboratory report. Ask your healthcare professional what the result means for you and your infant.
