Sanlor Marina Laboratory History

Sanlor Marina Laboratory begins with the enterprising spirit of Genaro Ruan Arias a Chemist Bacteriologist and Parasitologist who after having finished his studies at the National Polytechnic Institute of Mexico City, abbreviated IPN, and after working in important hospitals, decided to become independent and move to the state of Michoacán, where he opened his first clinical laboratory in 1979.

After the opening, he began to realize the lack of medical services in neighboring towns and decided to build some branch offices in the region. Time passed, and in the year 2000, the horizons of Sanlor Marina Laboratory expanded with the opportunity to establish for the first time inside a hospital in the beautiful city of Puerto Vallarta.

Years later, in 2003 we opened our laboratory in Hospital CMQ City Center, in 2008 inside Hospital CMQ Premiere and in 2017 in the new Hospital CMQ Riviera Nayarit. We have worked for more than a decade with Hospitals CMQ, doctors and specialists, providing our patients with the best and most efficient service.

Types of Lab Tests


Chemistry lab tests are a group of tests that are routinely ordered to determine a person’s general health status. They help evaluate the status of several major body organs. The chemistry lab test is performed on a blood sample, usually drawn from a vein. Common tests analyzed in the chemistry laboratory:

  • Glucose
  • Cholesterol
  • Blood urea nitrogen (BUN)
  • Creatinine
  • Potassium
  • Liver and heart enzymes
  • Thyroid
  • Hormones
  • Prostate-specific antigen (PSA)


Hematology lab tests study the blood, blood morphology and blood disorders. A hematological lab test can help diagnose anemia, various infections in the blood, hemophilia, blood-clotting disorders, and leukemia. Common hematology tests:

  • Complete blood count (CBC)
  • White blood cell count (WBC)
  • Red blood cell count (RBC)
  • Platelet count

Microbiological Analysis

Microbiological analysis study diseases caused by microorganisms. Microbiology identifies infectious agents in tissues, bone marrow, urine, blood, feces, and other body fluids. These microorganisms can include bacteria, fungi, parasites, and viruses. Common microbiological tests:

  • Blood culture
  • Stool culture
  • Urine culture
  • Burn, tissue, and wound culture
  • Throat swab
  • Nasal swab

Transfusion Services

The transfusion services provided by Sanlor Marina Laboratory work from the process of collecting blood through a donation to testing, processing, storing and transfusing blood and its components. These services can help treat severe anemia, cancer, and bleeding disorders, by providing red cells, plasma or platelets.


Immunology is the study of the body’s immune system and its functions and disorders. Immunology lab tests focus on identifying antibodies, investigating problems with the immune system and determining organ, tissue, and fluid compatibility for transplantation. The common immunology tests are:

  • Immunoglobulins
  • Rheumatoid factor
  • Human leukocyte antigens typing (HLA)

Surgical Pathology

The study of tissues removed from patients during surgery to help diagnose a disease and determine a treatment plan. Surgical pathology includes both the physical exam of the tissue and a processed exam under a microscope. This is ideal to distinguish between benign and malignant white blood cells, detect early genetic changes that may result in cancer, and to identify infectious agents in body tissues.


Cytology lab test evaluates specimens from various body sites for the detection of cancer, precancerous changes, and other benign conditions. It’s also used to screen fetal abnormalities, pap smears, and to diagnose infectious organisms. The most common type of specimen processed in the Cytology department is the Pap smear.

Genetic Toxicology Testing

Genetic toxicology studies are conducted to assess the potential for induction of genetic mutation or chromosomal damage. This type of testing is required for all classes of chemicals and drugs, and are of great importance because genetic damage can cause an increase in the incidence of heritable diseases and cancer in human populations. The most common types of genetic toxicology testing are:

  • Ames Assay
  • In vitro Chromosomal Aberration Assay
  • Mouse Lymphoma Gene Mutation Assay

Blood Bank

Blood banking is the process of collecting, testing, processing, and storing blood for later use. Sanlor Marina Laboratory ensures the safe use of the collected blood and its components.

How Do I Prepare for a Lab Test

Sanlor Marina Laboratories staff is always willing to help you have the best experience possible. Nonetheless, arriving prepared can help make your visit go smoothly. After all, the most important factor in determining the accuracy and reliability of your lab test result is you. Therefore, here are some simple steps you can follow for success during your visit:

  • Bring your doctor’s order. Although not obligatory, is better if you bring a note from your health provider with the specifics for your lab tests. 
  • Schedule your appointment. Minimize your wait by making an appointment. We do allow walk-ins, but having an appointment is the preferable way, as we can give you some instructions you can follow before your test. 
  • Arrive early. If you have an appointment, we recommend you arrive at least 10 minutes early to the set date. If you’re a walk-in, one thing to keep in mind is that our lab is at its full capacity in the mornings. 
  • If you’re having a blood test, make sure you drink plenty of water. Not taking in enough fluids can make your body dehydrated and this may affect some test results. Find out here some unusual signs of dehydration.
  • Inform your phlebotomist if you are taking any medications, such as anticoagulants (blood-thinners). 
  • Follow instruction. Some tests, like cholesterol and glucose, require fasting for at least 8 hours or even overnight. Other tests may require you to increase or decrease the amount of water you drink for 10 to 12 hours prior to the test.
  • Eat breakfast. Unless fasting is a must for your test, eat breakfast to help you keep your blood sugar up. 
  • Relax. If you are feeling anxious about what is going to happen, we recommend you ask the person taking your sample what he or she is going to do. Keep in mind that Sanlor Laboratories at Hospitals CMQ have highly trained staff ready to assist you if any problem arises. 
  • Bring something to eat and drink. After you have your blood drawn you can immediately have a snack and resume your regular diet after your test. 
  • The bandage can be removed after an hour of the test. Bruising may occur at the blood draw site. Apply some ice and give it time. 

It should be noted that many tests require no special preparation. But for those that do is better to ask your provider to give you a written copy with the instruction to follow. One of the more common types of preparation required for testing is fasting for several hours before the test or even overnight. Another important thing to know is that if you are collecting the sample from your home such as urine, stool or semen, you could be asked to follow certain procedures to transport the sample from home to the lab.

A culture media is a special medium used in microbiological laboratories to grow different kinds of microorganisms. Culture media contains all the elements that most bacteria need to grow. There are many types based on what nutrients they contain and what function they play. A culture media might be solid or liquid, some types of culture media in microbiology include:

  • Preservation Culture Media: composed of all the basic nutrients required for a microbial growth that is used to preserve a specific type of microorganism. 
  • Enrichment Culture Media: liquid media that allows the microorganisms to multiply and has the essential nutrients that are required for it. 
  • Selective Culture Media: allows the growth of certain microorganisms while inhibits the growth of the others. 
  • Differential Culture Media: used for differentiating bacteria by using identification markers for a specific type of microorganism. 
  • Resuscitation Culture Media: used for growing microorganisms that have lost the ability to produce due to harmful factors. 
  • General Purpose Media: has multiple effects, it can be used as a selective, deferential or a resuscitation media.
  • Isolation Culture Media: a simple agar containing solid medium that allows the growth of microorganisms in the direction of the streaks. 
  • Fermentation Media: liquid selective media used to obtain a culture of a specific organism like yeast or a particular toxin.

A urinalysis is a group of physical, chemical and microscopic tests that detect and measure several substances in the urine. With a urinalysis, many disorders may be detected in their early stages by identifying substances that are not normally present in the urine. A complete urinalysis consists of three phases:

  • Visual examination to evaluate the urine’s color and clarity.
  • Chemical examination for substances that provide valuable information about health and disease and determines the concentration of the urine. 
  • Microscopic examination, which identifies and counts the bacteria and other components that can be present in urine.

Urinalysis results can have many interpretations. However, normal values are:

  • Color: Yellow (light/pale to dark/deep amber)
  • Clarity/turbidity: Clear or cloudy
  • pH: 4.5-8
  • Glucose: <130 mg/d
  • Ketones: None
  • Bilirubin: Negative
  • Blood: <3 RBCs
  • Protein: <150 mg/d
  • RBCs: <2 RBCs/hpf
  • WBCs: <2-5 WBCs/hpf
  • Bacteria: None
  • Yeast: None

Before your test, make sure to drink plenty of water. Nonetheless, drinking excessive amounts of water may cause inaccurate results. One or two extra glasses of fluid are all you need on the day of the test. You don’t have to fast or change your diet for these tests. It’s important that you are very clear with your doctor and tell him/her if you’re taking any medications or supplements as some of these can affect the results of your urinalysis.

A urine drug test, also known as a urine drug screen or a UDS, is a painless test. It analyzes your urine for the presence of certain illegal drugs and prescription medications. A urine drug test usually screens for:

  • amphetamines
  • methamphetamine
  • marijuana
  • cocaine
  • methadone
  • narcotics
  • benzodiazepines 

This test can help your doctor detect potential substance abuse problems.

One of the very first changes the body undergo from the earliest moments of conception is the production of the pregnancy hormone HCG (Human Chorionic Gonadotropin), which can be detected in your blood and in your urine. The amount of HCG increases rapidly and it doubles every 36 to 48 hours as your pregnancy progresses. The way a urine pregnancy test work is detecting HCG levels in your urine, giving exact results within minutes, indicating whether HCG has been detected or not.
