The phrase "alternative method to detect" is correct and usable in written English.
You can use it when discussing different approaches or techniques for identifying or discovering something.
Example: "Researchers are exploring an alternative method to detect early signs of the disease."
Alternatives: "different approach to identify" or "substitute technique for detecting".
We designed a cellular in vitro assay as alternative method to detect the presence of functional LPS.
IGF-1 levels have been proposed as an alternative method to detect pubertal growth spurt timing in comparison to Cervical Vertebrae Maturity Index (CVMI) staging in different populations.
The bacteria identification array was proven to be useful as an alternative method to detect and monitor target bacteria populations during food fermentation.
We also used an alternative method to detect the number of clusters by calculating the ad hoc measure: ΔK (the second order rate of change of ln P D) with respect to K; [38]), where the modal value of ΔK corresponds to the most pronounced partition of the data set.
OPPV quantitative PCR (qPCR) is an alternative method to detect lentivirus and provides both diagnostic and prognostic information [ 25- 27].
Endothelial colony formation has previously been used as an alternative method to detect endothelial progenitors in PBMCs [ 20].
In this case, radiolabeled amino acids are the alternative methods to detect malignant pleural mesothelial and other cancerous cells which overexpress unregulated amino acid transporters [ 21– 23].
For situations in which the interindividual variability in a continuous upstream indicator is high, alternative methods to detect adverse changes in the biologic parameter will need to be developed.
For this reason, it is necessary to develop alternative methods to detect what type of tissue (e.g. fat, nerve, blood vessels) is being operated on during a surgery.
We also developed an alternative library-based method to detect transposases using profile HMM searches.
