Assay

Metal purity test to confirm that the metal meets the standards for trading on a commodities exchange (commodities exchange center).

Assay

To test precious metals for their purity. This is important to commodities and futures involving precious metals, in which the quality of the underlying metals must be specified in the contract.

assay

A test to determine the purity of gold, silver, or other precious metals. Metals used for delivery of futures contracts must be assayed to verify that they meet standards established by the exchange on which the contracts trade.

These include 1) a complement-fixation test that is relatively insensitive because in 25% of patients complement-fixing antibodies are not detected and in 75% of patients these antibodies appear late after infection; 2) a seroneutralization assay for detection neutralizing antibodies that appear 14-21 days after onset of disease; 3) an immunofluorescence assay that uses CTFV-infected BHK-21 or Vero cells and is an easy and rapid test for detecting anti-CTFV antibodies; and 4) an enzyme-linked immunosorbent assay (ELISA) for immunoglobulin M (IgM) and IgG that appear concurrently or a few days after neutralizing antibodies (peak 30-40 days after infection), However, IgM titers decrease sharply after day 45.
