Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
The sample is placed in a very hot oven to combust all organic matter. The leftover inorganic matter (ash), is weighed back and reported as a percent. This is needed to calculate Calories and Carbohydrates, and is sometimes used for certain global regulations.
