I’m pretty sure the answer is A but if you already ruled that out try B
A laboratory report form should indicate when a specimen has been collected by capillary puncture because certain test outcomes change depending on the specimen source.
<h3>What is capillary puncture?</h3>
For certain tests that call for small amounts of blood, people of any age may undergo capillary puncture or capillary sampling from a finger, heel, or (rarely) an ear lobe. The procedure is, nonetheless, frequently utilized on pediatric patients. For capillary testing on an adult patient, the finger is typically the first choice. Heel's sides are only used in young and neonatal patients. In surveys or research projects, ear lobes are occasionally employed.

Hormones glucagon and insulin are produced in the alpha and beta cells respectively in the Islet of Langerhan in the pancreas. They are involved in the negative feedback system of blood glucose regulation in homeostasis.
GLUCAGON: when there is a low blood glucose concentration, the pancreas detect this and alpha cells produce and release glucagon. Glucagon causes the cells of the body to absorb less glucose from the blood. It also inhibits the process of converting glucose into glycogen (glycogenesis) and cause gluconeogenesis (process of converting amino acids/proteins and lipids/fats into glucose) and glycogenolysis (conversion of glycogen to glucose). Finally, glucagon decreases the rate of respiration so less glucose is required.
INSULIN: when blood glucose is high, insulin is released. Insulin binds with cell surface receptors of cells and activates the enzymes attached to the receptor. The enzymes cause a conformational change in the structural proteins that surround glucose transport protein containing vesicles, causing them to move out of the way so the vesicles migrate up to the cell membrane and glucose transport proteins can fuse with it. Thus, more glucose can be taken in by cells. Insulin also cause glycogenesis (converting glucose into glycogen) and inhibits gluconeogenesis and glycogenolysis.
Basically insulin decreases blood glucose concentration (eg. after eating) and glucagon increases it (eg. skipping breakfast in the morning)
Persons with Blood Type A have A type antigens and B type antibodies.
