A high Tg assay value
is expected to alert the clinician to reevaluate the case and possible change in management, including the need for additional therapy; nevertheless, these cases with positive WBSs and negative Tg values present a worrisome scenario.
Since that time the composite assay value
for a particular charge of lumber has been used to determine quality compliance both internally by treating plants and externally by third-party testing agencies (AWPA 1963, 1964, 1965, 1966).
To ensure reliability and accuracy of the proposed method, recovery studies were carried out by mixing a known quantity of the standard drug with the sample at three different levels (80%, 110%, and 120% of assay value
labeled as A, B, and C) with preanalyzed samples and contents were reanalyzed using the proposed method.
Fibrinogen, AT and vWF showed the most variation in assay value
ranges between capped and uncapped tubes, for the same reasons as discussed with biological variation.
The mass balance is process of adding together the assay value
and the level of the degradation products to see how closely these adds up to 100 % of the initial value with due to consideration of the margin of the analytical error the mass balance is also very useful in method validation.
Hair Analysis for Cocaine--Dichotomous categorical variable coded as "positive" or "negative." All hair samples with an assay value
at or above 0.5 ng/ml of cocaine were labeled "positive."
The purified product is derived from fermented soybeans ranging in molecular weight from 100,000 to 4,000,000 Daltons with an assay value
As there is no feedback on the API assay measurement, the system can report only if the API assay is trending toward the preset limits established in the set-up, or stop the tablet press, if the API assay value
exceeds preset limits.
The peak assay value
within this zone is 1260ppb gold (1.26 g/t).
The peak assay value
was 44.5g/t gold over 1 metre.

Of the samples collected, a sulphide-bearing float sample collected from a creek in the GT-2 mineral tenure returned a significant assay value
of 264 ppb Au (gold) and a 1740 ppm Cu (copper).
