Primary health care is conceived as a key approach to achieving health for all and must be implemented especially in the developing countries.

These strategies represent a comprehensive approach by the health sector to the promotion of health, prevention of disease, appropriate diagnosis, adequate treatment and measures for rehabilitation. For these strategies - preventive, promotive, diagnostic, therapeutic and rehabilitative components of health care, proper surveillance with a sound and efficient network of laboratories is essential. At present, Laboratory support at the Primary Health care level is not fully developed in the most developing countries and the programmes for continuous medical education and quality control are limited. In the case of emergencies like the present one in Asia , it is simply non adequate. 

At the same time, several communicable diseases and especially new several emergent diseases are prevalent in these countries, in relation to which early diagnosis and well - defined laboratory - based epidemiological information could yield favorable results for the patient as well as the community, particularly at the peripheral level.

ORLANDO SYSTEM Inc., USA, member ABSA and EBSA, (with its division in Europe), which developed this project in 2001, now ORLANDO Systems LLC, is proposing a Programme for a network of MOBILE MEDICAL, BIOLOGICAL and VETERINARIAN LABORATORIES - Containerized [medical laboratory - standard and extended], independent, towed or installed on a 4 WD truck, boat or any other platform + as a part of a Mobile Laboratories Network in the Developing Countries and other areas. 

The level of the Mobile laboratory must be equivalent in the "Standard version" to the Peripheral laboratory, and in its "Expanded version" to the Intermediate laboratory. Usage of Rapid Tests in the Mobile Peripheral laboratories will allow prompt patient management and better disease surveillance as primary health care.

The OSL Mobile BSL3+ Laboratories and Clinics will also support the control of the quality of water and food, the environmental pollution and its hazards and, if possible, monitor the various vertical national health programmes. One of the special tasks of Mobile laboratory is to participate to the control of bioterrorism - diagnosis and collection of specimens from area concerned by bioterrorism.

Some of the Identifiable diseases are: COVID-19, Coronavirus, EBOLA, SARS, MERS, HIV, Variola, Malaria, Cholera, Tuberculosis, Polio, West Nile , Hepatitis, Anthrax, Ebola, Botullinic Toxin and most Animal diseases like FMD, Bovine TB, etc.  Control of epidemic conditions like EBOLA, SARS, as far as human or animal farm infections are fully considered as part of this project, started in November 2001. The present requirements for protections for EBOLA, SARS (as of April 27th, 2003 and 2004) and MERS are met. Avian flu H types so far (5/2020) are also met.

The Mobile Medical Laboratory networks should be an integral part of National Health Service, and should be developed within its framework, in the pyramidal structure of laboratory network from the developing countries.

The level of the Mobile Medical Laboratory must be equivalent in the "Standard variant" to the peripheral laboratory, and in its "Expended variant" to the intermediate laboratory . Our lab project has gone a step further and raised the Safety Level to BSL2 as far the Hood and as some functions of the Lab itself. A low cost Level BSL3 model is also available.

In the organization of the Mobile Laboratory priority should be given to the appropriate technology and tests of clinical relevance, applicable to the local circumstances and conditions. Conventional laboratory tests, though sensitive and specific, are often time-consuming, difficult to perform and need many reagents and much and expensive equipments.

Therefore, there is a clear need to introduce more RAPID TESTING as simple, reliable, reproducible, and cost - effective via a Mobile delivery method. The introduction of RAPID TESTING in the Mobile Peripheral laboratories will allow prompt patient management and better disease surveillance, which will be a great support for primary health care.

Common diseases for which laboratories at this level can help include:

DIAGNOSIS
Diagnostic procedures available at this level depend on the resources, manpower and policies of the health services as well as the prevalent communicable and noncommunicable diseases. Appropriate technologies, need - based and comprehensively evaluated by the local health care services, should be used wherever possible.

- "standard variant"
- a " plain vanilla " system, with standard equipment and reagents (BSL1), about 3 to 3.5 meters, but with a limited cost; And an;
•  " Extended variant " - longer, 3.5 to 4 meters, with a built-in Sample entry and Decontamination room, with optional equipments and reagents, with BSL3, with Negative pressure, HEPA air filtering available, etc.
•  The applications are: for Human and/or Veterinarian use, Vaccinations, etc,  

Basic microscopic examinations at the standard level may include the following

- Faeces for exudates [amoebic/bacillary dysentery], trophozoites, ova and cysts;
- Vaginal swabs - wet preparations for Trichomonas and Gram stained smears for candidiasis;
- Urethral discharge - Gram stained smears for gonococci;
- Sputum - Ziel Neelsen stained smears for acid fast bacilli;
- Skin - Ziel Neelsen stained smears for acid fast bacilli [AFB] and direct wet preparations for fungi;
- Nasal smears for AFB [Ziel Neelsen stain];
- Blood films for malarial parasites and microfilaria [Romanowsky stain];
- Urine deposits for cells, casts and parasites;
- Pus and exudates - Gram smears for bacteria;
- Cerebrospinal fluid [CFS] - Gram stained smears for bacteria, wet preparations for parasites and cell count in counting chambers:
- Semen examinations;

Clinical chemistry examinations should include the following:

•  Urine examination for glucose, protein, ketones, bile pigments and salts; and pregnancy tests;
•  Faeces for occult blood;
•  Blood examination for glucose, protein, bilirubin, creatinine, etc

  Hematology examinations should include the following

•  Hemoglobin estimation;
•  Total leukocyte counts;
•  Differential white cells counts;
•  Erythrocyte sedimentation rates [ESR];
•  Packed - cell volume [PCV];
•  Platelet counts;
•  Raeticulocyte counts;
•  Peripheral blood smears for cells morphology.

Serology for indirect identifications of infection, by means of determinations of antigens and / or antibodies, by rapid tests [including ELISA], for:

•  Viral, bacterial and parasitic infections.

Additional examinations include those for water, food and environmental contaminations.

In some infections, referral to higher-level laboratories should include:

•  Dispatch of faecal samples, for cultures, in suitable transport medium in cases of cholera, dysentery, diarrhea, etc.;
•  Serum / blood samples for culture and serology;
•  Water, food and environmental samples for analysis and culture;
•  Dispatch of appropriate samples during outbreaks. Technicians at the periphery must be trained to respond rapidly and appropriately in cases of outbreaks.

The Mobile Medical and Biological Laboratories shall have a proper communication system, GSM, Radio, Satellite and conventional, for voice, data, video  - as well as a GPS unit - with the fixed, higher-level laboratories with regards to data collection, supervision and quality assurance. International connections will speed up help requests for diagnosis and verification.
