Potency Testing (For Pricing Click Here)

Our potency test offers a quantitative analysis of several common psychoactive compounds found in medicinal cannabis. 
Although hundreds of different cannabinoids have been identified in cannabis, our PREMIUM POTENCY TESTING establishes the amount of Tetrahydrocannabinol (THC), Tetrahydrocannabinol Acid (THCA), Cannabidiol (CBD), Cannabidiol Acid (CBDA), Cannabigerol (CBG) and Cannabinol (CBN),contained in a submitted sample of medical cannabis or cannabis product. 

Our PREMIUM POTENCY TESTING separates the acidic compounds from the neutral compounds and defines the decarboxylation ratio of a sample which is extremely helpful in formulations of a product and the dosing of a consumer. We recommend using our PREMIUM POTENCY TESTING for any edibles, tincture or topicals that will not be combusted during consumption.  We use an established scientific method using a High-Pressure Liquid Chromatography (HPLC) with a variable Wave Detector (VWD) for the separation and quantification of THC, THCA, CBD, CBDA,  CBG, and CBN

All results are submitted as a percentage of the dry weight of the entire sample.

With the use of Potency Testing we have the ability to help our clients with two of our most popular and important Special Services:

1.     Early Leaf Cannabinoid Ratio Detection Testing

Microbiological Testing (For Pricing Click Here)

Results in 48-72hrs! The same conditions that are ideal for the cultivation of cannabis are also ideal for the germination of hundreds of bacteria and fungi which are found in the water, soil and air.  We must remember that yeast and molds can grow in decaying vegetation and the residual moisture will also encourage bacterial growth.  Also under ideal conditions, some fungi can produce toxic metabolites known as mycotoxins (ex. Aflatoxin and Ochratoxin) which can infect immunocompromised humans and cause allergic, aflatoxin and pathogenic infections such as the disease Aspergillosis.  Because of this, microbiological hazards in cannabis absolutely need to be addressed.  If your cannabis and all infused products are not properly tested, the medicine you are consuming can be contaminated with a variety of harmful pathogens.  

For those with compromised immune systems, Microbiological contamination can be very harmful and dangerous to one's health.
PharmLabs Hawaii™ STANDARD Microbiological Screen is a series of tests that report the total amount of Yeast, Mold and Aerobic bacteria in a sample reported in Colony Forming Units (CFU).

PharmLabs Hawaii™ new and improved PREMIUM Microbiological Screen is compliant with the new Hawaii law and will include the detection of total Yeast and Mold, total Aerobic bacteria, Aspergillus sp; Salmonella; E.coli; Staphylococcus aureus; Pseudomonas aeruginosa; Aflatoxin (B1,B2,G1,G2). Using 3M petrifilm and differential selective medium technology, we can identify, detect and quantify these microbial contaminants as total plate counts (CFUs) and using ELISA technology, we can quantify in parts per billion (ppb) the exact amount of Aflatoxin and Ochratoxin present.  All assays are ISO certified for design and manufacturing and are included in the official methods of analysis of the Association of Official Analytical Chemists International (AOAC).  Currently, no other cannabis testing laboratory in the US offers a more comprehensive microbiological screen than PharmLabs™.

Because of this new microbiological package, we will now have the ability to screen for three of the largest food-borne pathogens which is especially important when it comes to the topic of edibles. Even forty-nine of the top fifty food companies in the US use 3M Petrifilm technology. Microorganisms in cannabis can be an indication of spoilage, levels of sanitation and the potential for human pathogenesis.  As a cannabis professional, we should advise all edible makers to test their product before it hits the dispensaries/store shelf and also seek consulting advice on how to properly package and store the edible to increase its shelf life.  All of these preventative actions can help prevent people from getting sick and also increase the credibility of the cannabis industry as a whole.

Residual Solvent Testing (For Pricing Click Here)

Our Residual Solvent Testing offers a quantitative analysis of 24 solvents commonly used in the extraction of cannabinoids to make concentrated forms of cannabis. If a cannabis concentrate is not purged properly to eliminate solvents used in the extraction process; the residual solvent can remain in the concentrate when used by patients. These residual solvents remaining in the concentrates can be very harmful when inhaled or ingested. Residual solvents are typically not acutely toxic but may have a long-term effect on exposed individuals. An exposed person may exhibit eye, nose, and throat irritation, nausea, headaches, dizziness, fatigue, allergic skin reaction and at higher levels can cause central nervous depression, respiratory and cardiac arrest. Click here for the permissible and restricted solvents in the manufacture of cannabis preparations, (taken from the American Herbal Pharmacopeial). We use an established scientific method using a Gas Chromatography Headspace Analyzer with a Flame Ionization Detector (GC/FID) for the separation and quantification of:

2-Propanol (Isopropanol, Isopropyl alcohol)3-Methyl-1-butanol
AnisoleButyl acetate
Ethyl acetateEthyl formate
Isobutyl acetateIsopropyl acetate
IsopropylbenzeneMethyl acetate
Propyl acetateTert-Butyl methyl ether


Pesticide Testing (For Pricing Click Here)

We test for 56 pesticides commonly used to grow cannabis. Our method for determining Pesticide concentration by LC-MS/MS is completely quantitative and involves an extensive sample prep procedure to ensure high sensitivity.  All samples are run with accompanying standard curves containing known concentrations of pesticide standards as well quality control samples to ensure high accuracy and precision.  The process begins by drying and pulverizing the plant material into a homogenous powder to ensure all parts of the flower are represented in the analysis.  The material is then extracted in a special solvent that solubilizes pesticides, and these compounds are then further separated from interfering compounds using additional purification steps.  We have developed our sample prep process independently in our lab and we do not use any commercially available system to extract pesticide from the flower.

Once the sample prep is complete, the sample is analyzed on a Triple Quadrupole Mass Spectrometer which is coupled to an HPLC (Agilent 1100).  Our quantitation range spans nearly 3 orders of magnitude, ranging from the low parts per billion up to 1 ppm for most of the compounds,  Calibration curves and quality control analysis ensure linearity in quantitation, and this analysis is included in the report.

Pesticide residues in cannabis that has been dried and is inhaled have a direct pathway into the bloodstream. Like other foodstuffs, contaminants consumed through foods mixed with cannabis may present an exposure hazard. It is logical to assume that the prohibition on the use of a federally registered pesticide would result in a zero tolerance or allowable residue on the consumed cannabis. However, three states allow cannabis to contain pesticide residues of any federally registered pesticide up to a level less than the lowest legal residue of the pesticide on food. Oregon has set a generally acceptable level of .1ppm. This allowance of pesticide exposure does not account for the lack of EPA review of cumulative risk or toxic body burden associated with the additional exposure to pesticide residues from cannabis. Inhalation of Pesticide Residues Very little peer-reviewed research has been published on the health and safety risks associated with pesticides on dried cannabis. However, the tests that have been performed show cause for significant consumer concern, particularly medical patients or those with elevated risk factors. Studies on tobacco provide good indications of the threats that may arise from smoking pesticide-laced products and, thus, the importance of state enforcement. A 2002 study, published in the Journal of Chromatography A, found that 1.5-15.5% of pyrethroid insecticides on treated tobacco is transferred to cigarette smoke. Significant levels of pesticide residues were found within the cigarette’s cotton filter. In addition to the transference of pesticide residue from the dried plant to the smoker, burning can cause pyrolysis (decomposition) of the pesticide, forming toxic mixtures or other toxic pesticide contaminants. Additionally, unlike most packaged tobacco products, cannabis is not typically filtered when its smoke is inhaled, and therefore smokers may expose themselves to much higher levels of pesticides and degradates.


Heavy Metals Testing (For Pricing Click Here)

Unfortunately, there is a potential of heavy metal exposure with the use of marijuana from cultivating the plant itself, its commercialization, and its intake methods. Soils used for growing marijuana outdoors are frequently in peri-urban locations or near abandoned industrial and mining sites. Consequently, the presence of pollutant metals such as lead (Pb), mercury (Hg), arsenic (As), cadmium (Cd) and even chromium (Cr) in the soil and water tend to be more pervasive. Certain locales have been found to introduce specific contaminants such as high levels of mercury (Hg) in a particular island brand, excessive sulfur (S) in plants cultivated near a paper mill or coal furnace, and even high levels of uranium (U) in regional phosphate fertilizers. Cultivation soils used indoors can also present problems especially if non-certified fertilizers and/or pesticides containing Pb or As are used. As cannabis is a commodity typically sold by weight, some street dealers have been known to deliberately "lace" product to increase its weight. Pb is commonly used for this and in excess amounts is visible due to its consistency and white color.

Terpene Testing (For Pricing Click Here)

Our Terpene Testing offers a quantitative analysis of 21 major terpenes found in cannabis. Why does certain cannabis strains smell and taste a certain way? Terpenes! Terpenes are a diverse group of organic HydroCarbons (C5H8), produced by a wide variety of plants. They are important building blocks for certain odors, hormones, vitamins, pigments, steroids, resins, essential oils, and CANNABINOIDS! Terpenes interact with each other synergistically for a range of different smells, qualities, and physical effects. 

There are over 120 different terpenes that can be manufactured by Cannabis, some only in trace amounts with others around 20 percent. Terpenes are produced in the Trichomes, which are the same glands where THC is produced, comprising between 10 and 20 percent of the total oils produced by the glands. About 10-29 percent of cannabis smoke resin is composed of terpenoids. 

In addition to many circulatory and muscular effects, some terpenes interact with neurological receptors, bind weakly to Cannabinoid receptors, alter the permeability of cell membranes and allow in either more or less THC and affect serotonin and dopamine chemistry (neurotransmitters).

We use an established scientific method using a Gas Chromatography Headspace Analyzer with a Flame Ionization Detector (GC/FID) for the separation and quantification of: 

Caryophyllene Oxide

Plant SEX Testing (For Pricing Click Here)

The Phylos Plant Sex Test analyzes DNA from seedlings to identify male and female plants within days of germination with absolute certainty.  Seedlings are ready to test just after the second set of serrated leaves appear ( usually around 7 days ). Once the seedling reaches this stage the samples are collected by removing one of the cotyledon leaves and smashing it on a collection card.  See instructions here.

We are ISO/IEC 17025:2005 Certified! So what does that mean?

ISO is an acronym for the International Organization for Standardization. ISO/IEC 17025:2005 are requirements for the competence of testing and calibration of analytic laboratories and is the main ISO standard used by testing and calibration laboratories. In most major countries, ISO/IEC 17025:2005 is the standard for which most labs must hold accreditation in order to be deemed technically competent. In many cases, suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited. Originally known as ISO/IEC Guide 25, ISO/IEC 17025:2005 was initially issued by the International Organization for Standardization in 1999. There are many commonalities with the ISO 9000 standard, but ISO/IEC 17025:2005 is more specific in requirements for competence. The ISO/IEC 17025:2005 standard itself comprises five elements that are Scope, Normative References, Terms and Definitions, Management Requirements and Technical Requirements. The two main sections in ISO/IEC 17025:2005 are Management Requirements and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the quality management system within the laboratory. Technical requirements include factors which determines the correctness and reliability of the tests and calibrations performed in the laboratory. Laboratories use ISO/IEC 17025:2005 to implement a quality system aimed at improving their ability to consistently produce valid results.[2] It is also the basis for accreditation from an accreditation body. You can trust that your testing results with PharmLabs™ will be accurate every time!
