As there are a number of places that do IVC for well under $200 and do the G6PD test I can assure you the $600 blood test regimen is bogus.
G6PD is an enzyme that helps your body deal with abnormalities in the blood, and having a deficiency should preclude you from getting high dose IVC (above 5g per hour). This is a blood condition of some patients whose ancestry primarily originates from countries where malaria is common. This hemolytic condition is more common among the following:
1 in 12 Greek Cypriot men,
1 in 5 African men,
1 in 10 African-Caribbean men,
1 in 5 Indian men,
1 in 30 Chinese men,
1 in 5 Thai men.
For women that rarity is squared (for example, 1 in 144 Greek Cypriot women compared to 1 in 12 Greek Cypriot men) because for women generally both parents must have the defect.
I am aware of a number of suspicious situations where the practitioner did not want to do IVC and the patient was told they were G6PD deficient despite not fitting into any of the groups above.
It is also worth noting for those who received high-dose IVC with G6PD deficiency, it has very rarely been fatal (after much research I've been unable to find a fatality), and those who've experienced the contraindication were usually back to full health within a week though it did require many transfusions and they were in bad shape for a day or so (See

"Low-Rate IVC" for All?
Conventional rates for IVC are usually from 10g/hr to 30g/hr. Although rarely known, and rarely done, most people with the G6PD deficiency and even renal/kidney/dialysis issues can still get low-rate IVC ... even up to the 3g/hour range, which is quite low by contemporary IVC standards, but this amount is still more than enough to provide *all* the benefits of the very high dose ... they just may need to do it for 2X as long (unabated) to approximate the same benefit (up to 4X longer if the oncological benefit is desired). African ancestry persons with G6PD deficiency are most tolerant of low dose IVC, while Asian ancestry persons with G6PD deficiency are the least tolerant of IVC.
