The phrase "a detectable drop" is correct and usable in written English.
It can be used when discussing a noticeable decrease in a quantity or measurement, such as in scientific or analytical contexts.
Example: "After the experiment, we observed a detectable drop in the temperature of the solution."
Alternatives: "an observable decrease" or "a noticeable decline".
After a detectable drop in their level of play, capped by consecutive losses to Pittsburgh and Colorado at the Garden last week, the Rangers had won two games in a row and appeared to be back on track.
The true prevalence of iron deficiency in a population, however, will be larger than the level of clinically detectable iron deficiency anaemia (WHO, 2001a), because most individuals are likely to be iron deficient long before there is a detectable drop in blood haemoglobin levels.
For example, in HT-29 cells 1 nM, 10 nM and 100 nM PGE2 all lead to a reduced phosphorylation of PKA substrates, indicative of a reduction in cAMP levels, while only 10 nM PGE2 induces a detectable drop in cAMP levels as measured by the radioimmunoassay.
An opportunistic study of right whales revealed a short-term but detectable drop in oceanic noise levels, which coincided with a measurable reduction in the whales' stress levels.
In contrast, B220-CD8+ T cells from lpr mice showed no detectable drop in the expression of the IL-6 receptor consistent with maintenance of the pStat3 response to IL-6.
Our data would suggest that the Caco2 transmembrane resistance assay is an insensitive test method for Toxin A as ≥ 460 ng/ml was needed to give a detectable trans-membrane electrical resistance drop whereas ≥ 150 ng/ml of Toxin B produced detectable CPE in HFF cells.
Bacteremia then dropped to below a detectable level after 15 weeks postinoculation for all monkeys (Technical Appendix Figure 2).
To wrap up, the strength drop during the preslip period likely causes a detectable magnitude of change in the amplitude of elastic waves transmitted through or reflected at the target natural fault.
Repeated cycles of slight thawing followed by a subsequent drop back in temperature can readily lead to a detectable deterioration in the texture of the ice-cream.
"There is a detectable shift in stance.
"Track was originally offered to Christina Aguilera," continued the subheading, with a detectable note of bathos.
