The phrase "a sensitivity of approximately" is correct and usable in written English.
It can be used when discussing measurements or values that are not exact but are close to a certain figure.
Example: "The experiment showed a sensitivity of approximately 0.5 nanometers, indicating a high level of precision."
Alternatives: "a sensitivity of about" or "a sensitivity near".
Current tests have a sensitivity of approximately 75 90%; skin prick testing may be more sensitive than blood tests for specific IgE.
The optimised assay had a sensitivity of approximately 200 RNA copies per ml.
The RT-LAMP-LFD assay had a sensitivity of approximately 100-fold higher than conventional PCR.
Ultrasonographic evidence is also used to confirm this diagnosis, and has a sensitivity of approximately 87% and a specificity of approximately 82% [3].
The fabricated pressure sensor showed a great potential in sensing a small change of pressure with a sensitivity of approximately 1.68%/kPa.
In the liver UCAs have been shown to have a sensitivity of approximately 80% for detecting hepatic metastases [4], which is comparable to multiphase multidetector CT.
Given that the assay uses a 2 mm disc from a spot of approximately 15 mm diameter this represents a theoretical sensitivity of approximately a single parasite (∼77 fg DNA).
Enlargement of round nodes beyond 8 mm is considered a positive finding with a low sensitivity of approximately 34 – 40%% and a moderate/high specificity (80 – 97 %) [ 9, 10, 12].
Taken as a whole, using the manufactured molecule template, the assay had a final sensitivity of approximately 36 synthetic genome copies per reaction, which equates to 144 genome copies per mg of tissue.
The transfer characteristics exhibited a pH sensitivity of approximately 30 mV/pH, which is comparable with the pH sensitivity of the conventional oxygen-terminated non-doped SGFET and the single-crystal BDD SGFET investigated in our previous work.
Although carrier testing for Tay-Sachs disease among the Ashkenazi population has a test sensitivity of nearly 100%, CF screening using the 23-mutation CFTR panel has a lower sensitivity of approximately 80% in Northern Europeans.
