All Catalogues of laboratory tests that are reimbursed by the GHS are posted on the HIO website. Table 1 of the Catalogue includes Biochemistry, Haematology, Immunology, and Microbiology tests and Table 2 of the Catalogue includes Molecular Pathology, Cytology and Genetic lab tests. Each lab test has a weighting coefficient (number of points). Actual reimbursement is calculated per month and depends on the budget of that specific month and the total number of points of tests performed and is publicised/communicated in the following month.
