The Nagalase Test
Nagalase is short for "alpha-N-acetylgalactosaminidase"

Nagalase is an enzyme that suppresses your immune system. (1) (2) (4) (5)

What do Chronic Fatigue Syndrome, Cancer, AIDs, Autism & Lupus have in common?

  • Viruses (like Influenza, HIV, Epstein-Barr and herpes zoster) secrete Nagalase. (1) (2) (9)
  • Cancer cells secrete Nagalase. (3) (4) (5)
  • Nagalase accumulates in the serum of cancer patients and its activity correlates with tumor burden, aggressiveness and clinical disease progression. (11)
  • Of 400 Autistic Children tested, 80% of them had high Nagalase. (6)
  • Chronic Fatigue is an immune system dysfunction, often with evidence of viral persistence. (7)
  • 33 x Systemic Lupus Erythematosus patients were found to have high Nagalase. (8)
  • Nagalase as a non-invasive way of evaluation of melanoma severity. (10)
High Nagalase indicates that your condition may be successfully treated with GcMAF.

Book Your Nagalase Test.

We organise the Nagalase Test in New Zealand.
The cost is $380 in Auckland. (Outside of Auckland will attract a secondary Lab charge, payable direct to them)
Blood is received by "Labtests", at 37- 41 Carbine Road, Mt Wellington, Auckland 1060.
Samples are frozen at -70°C and batched before transport to the Netherlands for testing.

For the South Island, contact at the Christchurch Public Hospital. Chris can organise the taking of the sample and the delivery of it to Labtests in Auckland.

Test Batch
The current batch opened on Monday the 4th of May 2015, and closes on Friday the 26th of June 2015 at 4pm. Blood must be received between these dates to be included in this batch.

Note: All patient information is held in strict confidence.

After booking your test, you will be taken to instructions for paying for the Nagalase Test.

On that page you will also need to download the forms necessary for ...
   37- 41 Carbine Road
   Mt Wellington, Auckland 1060.
   Ph: 09 574 7399
You (or your frozen lab prepared sample) can turn up anytime (that a batch is open) with the forms between the hours of 8AM to 4PM, Monday to Friday.

Currently we are aware that an intake of Niclosamide or Hydroxocobalamin, within five days of the blood draw interferes with the Nagalase Test results. Also, always draw blood for the Nagalase test, as far away as possible from your last GcMAF injection.

Results: It is normal for nagalase test results to be received around 6 weeks after the batch closes.
