微生物用哪个更标准？absent or ND

定性检测（如微生物）用Absence in x g，定量检测用not detected（简写N/D或N.D.）。N.D似乎不规范

23. If 10 g of sample is added to the initial broth for a test such as E. coli (4.2), but an amount is immediately subcultured into a second broth that is only representative of 1g of actual product and this broth is incubated. At the end of testing, can this test be classified, for a negative result, as "none detected per 10 g" or as "none detected per g".
The quantity that is pre-incubated is 1 g therefore the outcome of the test is "absence in 1 g". For Salmonella, you will note that an "absence in 10 g" test has been implemented.

也有“Absent in 0.1g or 0.1ml test sample”和“Absent in 1g”的例子
