Plates and Sheets As aluminum moves between rolls under pressure, it becomes longer and thinner, thus resulting in Aluminum Plate or sheets. One of the main differences between Aluminum Plate and sheets is that sheet metal is under .249â thick, while plate metal is .250â and above.. Another difference between Aluminum Plate and sheets has to do with the distinct applications for which they are used. Sheets. Sheet is the form of aluminum that is used the most often.
The results of some viral tests (antibody or antigen tests) are reported in titers. A titer is a measure of how much the sample can be diluted before the viral antibodies or antigens can no longer be detected.

There are three main types of viral load tests: 1  PCR â polymerase chain reaction (written as PCR RNA). This is the most widely used type of test. 2  bDNA â branched DNA. 3  NASBA â nucleic acid sequence based amplification.
