Clinical laboratories are a critical component of health care. Approximately 80% of physicians’ diagnoses are a result of laboratory tests, according to Kalorama Information, a healthcare market research firm.
Common routine tests include cholesterol level tests, HIV tests, pap tests, pregnancy tests, and substance abuse tests. Clinical lab testing is also used to monitor diseases and drug treatments. Specialty testing, which is often more costly, may include genetics, immunology, oncology, endocrinology, and other segments.
