What is this test?
This test measures the amount of calcium in orange juice that has been fortified with calcium. The abbreviation does not identify the analytical method or a standard patient specimen.
Why might I need this test?
It may be performed as part of a 30-day nutrition study or product assessment to verify the calcium content of the fortified orange juice. Your study team can clarify whether the result is used for quality control or participant monitoring.
How is the test performed?
A sample of the fortified orange juice is analyzed for calcium using a laboratory method selected by the testing laboratory. The abbreviation does not provide enough information to identify that method.
How do I prepare for the test?
Follow the instructions provided by the study or laboratory, including how and when to submit the sample. Do not dilute, heat, or otherwise alter the orange juice unless the laboratory specifically permits it.
Reference range
Adult: 8.5-10.5 mg/dLN/A
No special preparation required. Stay well hydrated.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A higher or lower result may reflect differences in the amount and uniformity of calcium added to the orange juice. It would not, by itself, establish that a person has high or low blood calcium; interpretation depends on how the test is used in the study.
Short name
