Which lab tests are reimbursed by the GHS and what is the amount of reimbursement?
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.
How can a laboratory be enrolled in the GHS, which credentials are required, and what is the duration of a contract with the HIO?
Clinical laboratories are required to contract with the HIO via the IT System and the Provider Portal and follow all the steps stipulated therein.  In order for a laboratory to conclude a contract, it must fulfil the minimum requirements set by the Laboratories Regulation posted on the HIO website.
Is it required to send the lab tests’ results to the HIO?
Lab tests’ results must be attached electronically as a pdf file (for all tests) and as a xml file (for some tests specified by HIO) with the reimbursement claim, in order to complete the payment to the laboratory.
What is the procedure for the introduction of a new test/method on the tests catalogue?
Doctors and laboratory tests providers who are contracted with the HIO may suggest to the HIO additions/removals/amendments of laboratory tests by filling in the form posted on the HIO website. HIO has the responsibility to examine the addition/removal/amendment of the test/method to the Catalogue.
Which lab tests can a laboratory perform without a referral from a doctor?
Laboratory tests that are not included in a doctor’s referral and that the laboratory may add and be reimbursed for, in order to complete the results, are included in the Catalogues posted on the HIO website and on the Provider’s Portal.  These are marked with the symbol of a square out of which an arrow is coming.
Questions regarding LOINC
The LOINC (Logical Observation Identifiers Names and Codes) standard is used for the codification of the lab tests included in the first Table of the Catalogue (Biochemistry, Haematology, Immunology, Microbiology).
Information on LOINC can be found at
Upon the GHS implementation what will be the procedure in order to request laboratory tests to be performed?
A Personal Doctor or an Outpatient Specialist enrolled in the GHS will issue a referral to beneficiaries for laboratory tests when he/she deems that the beneficiary’s health condition so requires for the purposes of diagnosis, monitoring, treatment or any other medical reason.  The doctor can issue via the IT System the relevant referral stating the tests to be performed by a laboratory.
Where can I find the GHS registered laboratories?
All registered laboratories with the GHS are posted on the HIO website.
Can I choose which laboratory will provide me with their services?
GHS beneficiaries may freely choose which laboratory will provide them with their services from the catalogue of registered laboratories posted on the HIO website.
Can I go directly to a laboratory of my choice for a general check-up?
In order for any tests to be performed it is required that the predetermined procedure is followed, i.e. visit to the Personal Doctor or Outpatient Specialist and if necessary a referral for lab tests.
Lab tests performed without a referral from an HIO contracted doctor are not reimbursed. 
How will I be informed about the results of my lab tests and who else has access to them/sees them?
The laboratory will post your results and these will be accessible via the Beneficiary Portal at your personal account.  The doctor who has referred you, any other contracted doctor you visit as well as any other laboratory you visit are informed and have access to your results.  In case you do not wish your lab tests’ results to be visible you must determine this using the settings of your personal account.  You must however have in mind that if you conceal data, it is possible that the healthcare service offered to you will not be the appropriate service and/or you may put your health at risk.  In addition, it is possible that a healthcare provider may refuse to serve you.
When will I receive my lab tests’ results?
For most tests the results are available on the same or the following day, especially for Biochemical, Haematological and Immunological tests.  Some tests (microbiological cultures) as well as more specialised tests, may take longer.  Your doctor or laboratory will be in a position to inform you on this.
For how long is my sample kept at the laboratory?
For most tests, samples are kept at laboratories for a few days in case a test must be repeated or an additional aspect tested.
Can my doctor refer me for any lab test?
For some tests there are some restrictions such as for example the doctor’s specialty who can refer to a particular test and/or whether the test is justified by your medical condition of the beneficiary.
