The more glucose in the blood, the more haemoglobin A1C or HbA1C will be present in the blood. The HbA1C test is currently one of the best ways to check diabetes is under control; it is the blood test that gets sent to the laboratory, and it is done on the spot in some hospital clinics.
In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not, even when derived from a proper noun such as the name of a person or place. Similarly, both parts are italicized when a binomial name occurs in normal text.
This is referred to as the binomial name and is the end point of the Biological Classification system. We always italicize the Genus, species (and capitalize Genus while leaving the species lower case). Sometimes you see a third name - the epithet of the species name. There is quite a bit of history behind the answer to this naming question, but the short answer is that the naming is based on a taxonomic system or code developed by Carl Linneaus in the 1700s.
