DOH ADMINISTRATIVE ORDER NO. 2015-0005

SUBJECT : Guidelines on the Performance Evaluation of In-Vitro Diagnostic Reagents (Human Immuno Deficiency Virus (HIV), Hepatitis B Virus (HBV), Hepatitis C Virus (HCV) and Syphilis Screening, Confirmatory and Disease Monitoring Test Kits)

 

I. Rationale

The use of the best and quality kits is imperative in providing proper diagnosis and in ensuring blood products are safe from blood-borne transmissible infections. In order to support proper diagnosis and blood safety accurate and reliable laboratory results should be released by the different clinical laboratory testing centers in the country of which this regulation purposely aims to improve. Certain test kits perform differently in specific geographic locations and differences in test performance have been reported depending upon the origin of the samples. Thus, there is a need for assessment and evaluation by an independent organization to determine the appropriateness of these test kits in our local setting. Assay evaluations indicate a "point-in-time" assessment of assay performance, therefore, continued monitoring of the assay's ongoing performance should also be implemented.

Pursuant to the provisions of Republic Act (R.A.) No. 3720 as amended by Republic Act (R.A.) 9711, test kits and in-vitro diagnostic reagents must be registered with the Food and Drug Administration (FDA) of the Department of Health before release into the Philippine market.

In accordance to Department Order No. 393E s. 2000, (Designation of National Reference Laboratories and Transfer of Corresponding Equipment, Instruments, Supplies, Specimens, Records from the Bureau of Research and Laboratories), the National Reference Laboratory STD AIDS Cooperative Central Laboratory (NRL-SLH/SACCL) of San Lazaro Hospital has been mandated to perform evaluation, validation and continuous monitoring of test kits in the diagnosis of HIV and other STIs to ensure their quality and good performance in local setting.

II. Scope/Coverage

These guidelines shall apply to all manufacturers, traders and distributors (importers/exporters/wholesalers) of all test kits and in vitro reagents used to screen, confirm and monitor HIV (antibody and/or antigen), HBV (HBsAg and other markers), HCV (antibody and antigen) and syphilis (Treponemal and non-treponemal) infections using serum, plasma or whole blood and other body fluid samples.

III. Definition of Terms

The following definitions shall apply:

1. Applicant — refers to a natural or juridical person that seeks to distribute HIV, HBV, HCV and Syphilis test kits/in-vitro reagents.

2. Center for Device Regulation, Radiation Health and Research (CDRRHR) — refers to one of the four centers of the Food and Drug Administration (FDA), mandated to regulate the manufacture, importation, exportation, distribution, sale, offer for sale, transfer, promotion, advertisement, sponsorship of and/or, where appropriate, the use and testing of medical devices including in-vitro diagnostic kits and reagents. aETADI

3. Confirmatory test — refers to tests performed on samples that are reactive by screening tests to ensure that the screening test results were accurate.

4. Distributor-Exporter — refers to any establishment that exports raw materials, active ingredients and/or finished products of screening test kits/reagents to another country.

5. Distributor-Importer — refers to any establishment that imports raw materials, active ingredients and/or finished products screening test kits/reagents for its own use or for wholesale distribution to other establishments or outlets within the country.

6. Initial registration — refers to company's application to register test kits that has never been registered locally.

7. Point-in-time assessment — an assessment done for a test system at that particular point in time when evaluation was performed, done by a technologist, using a pre-determined set of panel sera and reagent lot for testing. As such, results of succeeding evaluation done at a different time on the same or different panel may not necessarily produce identical results.

8. Manufacturer — refers to any establishment involved in the production of an in-vitro diagnostic medical device including processing, formulating, packing, re-packing, finishing and labeling with the ends in view of its storage, sale or distribution.

9. Renewal registration — refers to company's application to renew their registration on or before the expiration of their Certificate of Product Registration.

10. Reactive — refers to the reported test result from a screening test that indicates presumptive evidence of infection.

11. Sensitivity — means the ability of a test to detect very small amounts of analyte, or the ability of a test to detect infected individuals.

12. Seroconversion — the point at which specific antigen/antibody can first be detected in an infected individual who was previously found negative of HBV, HCV, HIV and Syphilis.

13. Specificity — means the ability of the test to identify negative samples.

14. Trader — any establishment which is a registered owner of a health product and procures the raw materials and packing components, and provides the production monographs, quality control standards and procedures, but subcontracts the manufacture of such product to a licensed manufacturer. In addition, a trader may also engage in the distribution and or marketing of its products.

15. Validation — a process done to monitor the performance of previously approved screening test kits and verify performance of other special test systems.

16. Screening test system — an initial test used in a population to identify a disease in individuals with or without signs or symptoms.

17. Other test system — test other than screening test, used to monitor/stage infection

a. Confirmatory/Supplemental tests

For a screening test system to be considered acceptable for registration, it must meet the following recommended requirements set by NRL-SLH/SACCL:

a. Sensitivity (in performance assay)

- the ability of a test system to give a positive result in the presence of the target marker;

- the ability of a test system to detect the smallest amount of the target marker that can be precisely detected.

b. Specificity (in performance assay)

- the ability of a test system to give a negative result in the absence of the target marker;

- the ability of the method to determine solely the target marker.
