These analyses can include measuring levels of specific substances such as glucose or cholesterol, identifying infectious agents like bacteria or viruses, and screening for genetic abnormalities.

Blood test work results are typically available within a few days after collection. It’s important to note that interpreting these results requires specialized knowledge and training–a doctor or other healthcare professional should always be consulted if there are any concerns about them.
