Test report or laboratory report is written to record the results of tests and experiments. When you write a test report, it is important to take careful notes because the accuracy of test report is essential. A test report can be a letter or memorandum. See sample test report below.

Dear Mr. Hite:
On Tuesday, August 30, Biospherics, Inc. performed asbestor-in-air monitoring at your Route 66 construction site, near Front Royal, Virginia. Six persons and three construction areas were monitored. In every case, exposure was well below the standards set by the National Institute for Occupational Safety and Health (NIOSH) in 1972.
All monitoring and analyses were performed in accordance with “Occupational Exposure to Asbestos, “U.S. Department of Health, Education, and Welfare, Public Health Service, National Institute for Occupational Safety and Health, 1972. Each worker or area was fitted with a battery-powered personal sampler pump operating at a flow rate of approximately one liter per minute. The airborne asbestos was collected on a 37-mm Millipore type AA filter mounted in an open-face filter holder. Samples were collected over an 8-hour period.
A wedge-shaped piece of each filter was mounted on a microscope slide with a drop of 1:1 solution of dimethyl phthalate and diethyl oxalate and then covered within 24 hours after mounting, using a microscope with phase contrast option.
In all cases, the workers and areas monitored were exposed to levels of asbestos fibers well below the NIOSH standard. The highest exposure found was that of a driller who was exposed to 0.21 fibers per cubic centimeter.
The driller’s sample was analyzed by scanning electron microscopy followed by energy dispersive X-ray techniques which identify the chemical nature of each fiber, thereby verifying the fibers as asbestos or identifying them as other fiber types. Results from these analyses show that the fibers present are tremolite asbestos. No nonasbestos fibers were found.
Yours truly,
Gary Willis
