Lab Tests




Precision Analytical DUTCH hormone test panels provide you with detailed information on how adrenal and sex hormones are being produced AND metabolized in the body. DUTCH stands for Dried Urine Test for Comprehensive Hormones.


Precision Analytical DUTCH Complete test panels:

  • DUTCH Adrenals (daily free cortisol and cortisone pattern, DHEA-S, cortisol and cortisone metabolites)
  • DUTCH Sex Hormone Metabolites (androgens and metabolites – testosterone, DHT, DHEA; progesterone metabolites; estrogens and metabolites)
  • DUTCH Melatonin


  • Test Type: Dried Urine (urine is collected onto filter paper strips at 4 specific times throughout the day)
  • Shipping: Use the envelope enclosed in the test kit, affix 6 stamps to it, and send it back to the lab by regular mail.
  • Cost: DUTCH Complete: $250 in the US and Canada.  For all other countries please add $25 per test.  Shipping back to the lab will be extra from international locations.

  • Turnaround Time: 5-10 business days

Advantages of this test:

  • In addition to measuring daily free cortisol levels (the amount of available cortisol circulating in the body), the DUTCH test tells you about metabolized cortisol (the amount of cortisol the adrenals are producing or clearing), sex hormone levels, whether phase I (hydroxylation) and phase II (methylation) of estrogen metabolism is good or poor, and if DHEA and testosterone are being pushed down the more androgenic pathways.
  • Because the DUTCH test kit is small, dried urine is fairly stable, and samples are mailed back to the lab in a standard envelope, the DUTCH Complete may be a less expensive adrenal/hormone test for those who are overseas. 




The Diagnostic Solutions Laboratory GI Microbial Assay Plus (“GI-MAP”) includes markers for gluten sensitivity (anti-gliadin IgA), inflammation in the gut (lactoferrin), immunity in the gut (SIgA), pancreatic enzyme sufficiency (elastase), and occult blood. It also looks for the presence of pathogens – including H Pylori and other bacteria, parasites, and viruses – in the gastrointestinal tract.
  • Bacterial Pathogens (Campylobacter, C difficile Toxin A & B, E coli 0157, Salmonella, Shiga-like Toxins, Shigella, etc.)
  • Parasitic Pathogens (Cryptosporidium, Entamoeba histolytica, Giardia)
  • Viral Pathogens (Adenovirus, Norovirus, Rotavirus)
  • H pylori (H Pylori, cagA, vacA)
  • Normal Bacterial Flora (Bifidobacter, Enterococcus, E. coli, Lactobacillus)
  • Opportunistic Bacteria (Citrobacter, Klebsiella, Proteus, Yersinia, Pseudomonas, Staphylococcus, etc)
  • Parasites (Blastocystis hominis, Dientamoeba fragilis, Endolimax nana, Entamoeba coli, Chilomastix mesnelli, etc.)
  • Fungi/Yeast (Candida albicans, Candida spp., Geotricum spp., Microsporidia spp., Trichosporon spp.)
  • Additional Tests (SIgA, Anti-Gliadin, Elastase, Lactoferrin, Occult Blood)
  • Antibiotic Resistance Genes

To detect pathogens, the lab uses PCR (Polymerase Chain Reaction) technology to detect the DNA of microorganisms.

  • Test Type: Stool (1-day single specimen collection)
  • Shipping:
    • Within the U.S. or Canada, use the FedEx shipping bag enclosed in the test kit and drop the package off at a FedEx office or call FedEx for a free pick-up.
  • Cost:
    • Pre-pay cash price is $359 for U.S. clients. Insurance is an option with DSL. When using the insurance option please client must include the $179 deposit along with a copy of their insurance card.  If client’s insurance company covers the cost of the test, the $179 deposit will be refunded.  If client’s insurance does not cover the cost of the test client will be mailed an invoice from Diagnostic Solutions Laboratory.  Please be aware that the invoice amount may be greater than the cash pay price ($359).  In this instance client can contact DSL using the number on the invoice and request a “Prompt Pay” discount which will be the cash pay price minus the original deposit.

  • Additional info:
    • Clients must complete all highlighted sections of the Test Requisition Form and include a copy of the front and back of the insurance card.
    • Do not add diagnostic codes to the form. 
    • The lab recommends refrigerating the specimen if it will not be shipped the same or next day.
    • The lab must receive the sample within 6 days of collection (for the SIgA result to be valid). The DNA for the pathogens part of the panel is stable for up to 2 weeks, however.
    • The client does NOT need to be off anti-microbials (antibiotics or herbal supplements) prior to collecting the stool sample.
    • The client should AVOID taking aspirin for 2 days prior to collecting the sample.
    • An H pylori only re-test is available (“H Pylori Profile”)
      • Cost: Pre-pay cash price is $109; Insurance billing deposit is $59.
    • The turn-around time to receive the results back is 21 business days from when the lab receives the sample

Advantages of this test:

  • The GI-MAP is the first FDA-approved DNA/PCR assay for GI pathogens, making the results more widely accepted.
  • PCR technology provides the ability to identify bacteria, parasites, viruses, and fungi regardless of their viability in the sample. Stool cultures grow only aerobic bacteria but 95% of the bacteria in the digestive system are anaerobic, including the pathogens. It is not possible to measure strict anaerobes, viruses, or virulence factors with a culture based test. Parasites need to be in high numbers to be detected by microscopy, so there are times when O&P (Ova & Parasite) testing may miss pathogens that might be detected by PCR.
  • It tests for H pylori and identifies if the H pylori is one of the more virulent strains (cagA or vacA) which has been associated with ulcers and gastric cancer.
  • DNA/PCR assays are superior at detecting Giardia and E histo, as very low amounts of these parasites are typically shed in the stool.
  • DNA/PCR assays are far more sensitive in picking up Candida than culture based stool tests.
  • In addition to looking for pathogens, this test panel contains several additional markers which can provide invaluable insight into gut immunity (SIgA), gut inflammation (lactoferrin), pancreatic enzyme sufficiency (elastase), and gluten sensitivity (anti-gliadin).
  • This panel is more comprehensive (contains a lot more markers) than most other available pathogen stool tests.
