Systems, methods, and machine-readable instructions stored on machine-readable media are disclosed for receiving a first DNA sequencing result and a second DNA sequencing result, wherein the first DNA sequencing result is a result of a first DNA sequencing technique and the second DNA sequencing result is a result of a second DNA sequencing technique. A difference is determined between the first DNA sequencing result and the second DNA sequencing result. Parameters are scored corresponding to the first DNA sequencing result and to the second DNA sequencing result, wherein the scoring includes: determining a value range of a parameter in a set of reference parameters corresponding to a value of a corresponding parameter of the parameters; and assigning a score associated with the value range of the parameter in the set of reference parameters as a score of the corresponding parameter. A determination is made that the first DNA sequencing result or the second DNA sequencing result is conclusive or inconclusive based on respective scores of the parameters of the first DNA sequencing result and the second DNA sequencing result. An indication is made to perform a third DNA sequencing using a third DNA sequencing technique when the first DNA sequencing result or the second DNA sequencing result is inconclusive.
