TSH stands for thyroid stimulating hormone. A TSH test is a blood test that measures this hormone. The thyroid is a small, butterfly-shaped gland located near your throat. Your thyroid makes hormones that regulate the way your body uses energy. It also plays an important role in regulating your weight, body temperature, muscle strength, and even your mood.

The C-reactive protein (Quantitative) test measures the levels of C-reactive protein in blood to determine the presence of inflammation or infection and to monitor treatment.
