You're already used to having your blood drawn at the doctor's office. It's simple. A clinician jabs your vein with a hypodermic needle while you squeamishly look the other way, extracts a sample, and in less time than it takes to find a parking spot at the doctor's office, you're done.
Typical blood work can tell physicians a lot of things –- your cholesterol and blood sugar levels, kidney and liver functions, and can reveal enzyme markers for certain diseases as well. Guardant Health (NASDAQ: GH) and Roche Holding (OTC: RHHBY) are taking the simple blood test to a new level, helping medical professionals better target the treatments of certain types of cancers through liquid biopsies that use blood or other fluids to track how those cancers grow and change.
