The following are the service capabilities of hospital-based secondary laboratories, EXCEPT:

Hospital-based secondary laboratories typically provide a broad range of diagnostic services, including routine testing for various conditions. Routine chemistry tests, electrolytes, and complete blood count (CBC) fall within the common capabilities of these laboratories.

Routine chemistry encompasses a variety of tests that assess organ function and metabolic states, making it essential for patient management. Electrolyte testing is crucial for monitoring and diagnosing conditions related to fluid and electrolyte imbalances, which is routinely performed in such settings. The complete blood count is a fundamental test in clinical laboratories used to evaluate overall health and detect a wide range of disorders, such as anemia and infection.

In contrast, arterial blood gas (ABG) analysis is generally more specialized and is often conducted in critical care settings or by laboratories that have the specific infrastructure and expertise required to handle and analyze such samples accurately. While secondary laboratories may perform these tests, they are not as routinely available in every secondary lab compared to the other tests listed. Thus, this distinction makes arterial blood gas testing less characteristic of the typical services provided by hospital-based secondary laboratories.
