HDL/LDL and Total Cholesterol
These scan for heart disease. As a bodybuilder, you likely carry around a high bodyweight, and you likely consume a fair deal of cholesterol via eggs or red meat. Watch these levels, as half of Americans do die from heart failure, and bodybuilders are a high-risk group.
Homocysteine
Anabolic steroids cause high Homocysteine levels. This amino won't always be monitored in a blood screen, but as a bodybuilder, you should follow it. Homocysteine levels in the high range can mean you are in a high-risk group for heart disease. Taking your B vitamins daily reduces these levels.
Hemoglobin Profile
These are standard blood analysis tests and are used to discover serious diseases.
White Blood Cell Total
These are known as leukocytes, and their levels are indicative of cancers, stress, and other taxation of the immune system.
Red Blood Cell Count
If you use steroids and you have high red blood cell values, you are at risk for a heart attack.
Hemoglobin
Hemoglobin delivers oxygen and carbon dioxide to the body. Use of anabolic or androgenic agents can cause an increase in this count, which can reveal higher instances of kidney disease, cancer, or anemia.
Platelets
Platelets help your body to form blood clots and stop bleeding. High platelet levels mean you should consult a specialist immediately and see what the minor problem could be. Low platelet levels are more serious, and can be indicative of diseases such as anemia or leukemia.
Sodium
Bodybuilders will often manipulate sodium levels before shows, and many will use this practice off-season as well. The use of diuretics is also one of the key reasons that many bodybuilders suffer from kidney failure. And one cannot forget the supplements we take on a daily basis, which must be filtered by the kidneys.
Standard blood tests study many other factors. This is just a starting ground. If you use anabolic steroids, you should have your blood work checked immediately, then yearly, to ensure you are keeping yourself healthy.
