Question

In relation to Pregnancy kit, answer the following:

A- Explain how pregnancy kit is considered as a “biosensor” technology? (1%)

B- What is the biological sample required for test: blood serum, blood plasma, saliva, urine? (1%)

C- What is the name and the nature (protein, carbohydrate, nucleic acid?) of molecule that this pregnancy kit is detecting? (1%)

Answer 1

Question no 1

A biosensor based on one of the interferometer techniques, Mach-Zhender interferometer (MZI) technique, and the using of the laser beam is developed for pregnancy detection or pregnancy hormone, Human chorionic gonadotropin (HCG), increasing

A simple example is a pregnancy test biosensor where researchers from biology highlighted the biological aspects and co-operated with engineers to work on the electronics of the system for the read-out.The bioelement interacts with the analyte being tested and the biological response is converted into an electrical signal by the transduce

Part b

Human blood for blood serum

serum albumin test can tell your doctor how well your liver is working. It's often one of the tests in a liver panel. In addition to albumin, a liver panel tests your blood for creatinine, blood urea nitrogen, and prealbumin.

Human blood for plasma

Plasma protein tests are blood tests that detect the amount of proteins in the blood. This lab work is usually ordered as part of a comprehensive metabolic panel (CMP) during a physical exam. The tests can help your doctor determine your overall health. Plasma protein tests are also known as a total protein test.

Urine testing

Urine samples must be collected in such a manner that contamination of the specimen is avoided and transported to the laboratory for analysis under appropriate conditions. Typically, a 50 ml urine specimen is collected and should be sufficient for 2-3 tests per sample.
