- Taxonomy Description
- (1) A clinical laboratory is a facility for the biological, microbiological, serological, chemical, immunohematological, hematological, biophysical, cytological, pathological, or other examination of materials derived from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of any disease or impairment of, human beings. These examinations also include procedures to determine, measure, or otherwise describe the presence or absence of various substances or organisms in the body. Facilities only collecting or preparing specimens (or both) or only serving as a mailing service and not performing testing are not considered clinical laboratories. (2) Any facility that examines materials from the human body for purposes of providing information for the diagnosis, prevention, or treatment of any disease or impairment of, or the assessment of, the health of human beings. Typical divisions of a clinical laboratory include hematology, cytology, bacteriology, histology, biochemistry, medical toxicology, and serology.

A direct bilirubin test measures a form of bilirubin in your blood. Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels may indicate liver or blood disorders. This test helps diagnose and monitor these conditions.
This service was performed 66 times for 20 patientsA basic group blood test measures the levels of certain chemicals in your blood, including calcium. This helps assess your overall health and detect potential problems. The procedure involves drawing a small amount of blood from your arm, which is then analyzed in a lab.
This service was performed 110 times for 92 patientsA clotting time blood test helps determine how quickly your blood forms clots, a process crucial to stop bleeding. During the test, a small blood sample is taken from your arm. The sample is then analyzed in a lab to see how long it takes for a clot to form.
This service was performed 122 times for 80 patientsA comprehensive group of blood chemicals test, also known as a comprehensive metabolic panel, is a blood test that measures your sugar level, electrolyte and fluid balance, kidney function, and liver function.

It helps assess overall health, detect disorders like anemia or infection, and monitor medical treatments.
This service was performed 17 times for 15 patientsA Complete Blood Cell Count is a common test that measures various components of the blood, including red cells (carry oxygen), white cells (fight infection), and platelets (help blood clot). An automated test ensures accuracy. The differential count provides detailed information about white cell types.
This service was performed 379 times for 256 patientsThis procedure involves inserting a small needle into a vein, typically in your arm, to collect a blood sample. It's a quick and simple process to help diagnose or monitor health conditions. You may feel a small prick, but discomfort is minimal.

Phosphate is a chemical that contains the mineral phosphorus, crucial for energy production, muscle and nerve function, and bone growth. Imbalances may indicate kidney disease or other health issues.
This service was performed 46 times for 29 patientsThe Red Blood Cell Sedimentation Rate is a test that helps detect inflammation in the body. It's automated, meaning a machine does the work. This test measures how fast red blood cells settle at the bottom of a tube in an hour. A faster rate may indicate inflammation.
This service was performed 49 times for 33 patientsA blood uric acid level test measures the amount of uric acid in your blood. Uric acid is a waste product that your body produces when it breaks down purines, substances found in your body and in certain foods. High levels may lead to gout or kidney stones.

NPI NPI Number Validation
How NPI Validation Works
The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.
To verify the NPI 1508905829, we treat the final digit (9) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 61. The final step is to find the difference between that total and the next multiple of ten (70 - 61 = 9).
Digit-by-digit view
Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.
Step 1: Double every other digit from the right
Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.
Step 2: Add all digits plus the NPI constant
Add the transformed values, the unchanged digits, and the constant 24.
Step 3: Find the amount needed to reach the next multiple of 10
The next multiple of ten after 61 is 70. The difference is the calculated check digit.
