Why You Should Not Rely on Blood Tests for Hormone or Nutrient Levels

[Guest guest]

Revised with clarifications March 28, 2011.

Your circulatory system, also known as the cardiovascular system, is the system

that, in humans and other higher animals, delivers oxygen, hormones and

nutrients throughout the body by a complex network of vessels, and it carries

carbon dioxide and waste products from the cells to organs that get rid of them,

which are mainly through the lungs, liver, kidneys and skin.

The circulatory system has three main types of blood vessels:

1) arteries

2) veins

3) capillaries (very tiny blood vessels only 1 cell thick)

Arteries contain oxygen from the lungs, nutrients from the digestive system,

hormones, etc. that they circulate throughout the body.

Veins carry deoxygenated blood (carbon dioxide), waste products from the cells,

and any nutrients or hormones the cells did not uptake. It carries carbon

dioxide to the lungs for release, along with any other waste products the lungs

get rid of, and it circulates to other organs that get rid of toxins and waste,

i.e. liver, kidneys, skin, etc.

Arteries and veins meet at the capillaries; artery blood on one side and vein

blood on the other side like the image in this link on the right:

Artery blood transfers its blood to the capillaries, and the capillaries

transfer oxygen, nutrients, hormones, etc. to the cells so they can take what is

needed or they can use.

On the other side capillaries intake waste products from the cells, along with

carbon dioxide, nutrients, and hormones that they transfer to the veins.

Blood tests are taken from the veins, so they cannot possibly reflect what is

going on at a cellular level, and it does not measure the amount of oxygen,

nutrients, hormones, etc. contained in artery blood and therefore the amount

that was taken in by the cells.

Because capillaries are so tiny, red blood cells must fold over in order to get

into them. However if the red blood cell membranes aren't healthy they are not

as able to fold over like they should.

This is particularly important in the intestines, so blood cells are able to

intake nutrients, transfer them to the arteries, to be circulated through the

capillaries for other organs/areas of the body.

Cell membranes of all cells are affected by two major things:

Notes: Tissues and organs are made up of many cells that are close together,

unlike blood cells that are separate unless they clot.

1) In order for cell membranes to be healthy they must be constructed out of 50%

saturated fat (lung cell membranes need 100%). If they aren't constructed

properly the cells become weak and are less able to intake oxygen, nutrients,

hormones, etc. and they lack the energy they need to get rid of their natural

waste products.

2) Toxins make cell membranes rigid/stiff so the cells are less able to uptake

nutrients, hormones, oxygen, water, etc. – see Toxins Cause Cell Membrane

Testing vitamin D levels in the blood has become popular these days, however

vein blood cannot reflect the amount of vitamin D that was available in artery

blood, so you wouldn't know how much your cells actually got.

Therefore testing your blood for hormones and nutrients like Vitamin D, iron,

calcium, B12, etc. is meaningless.

That is why it is so important to stick to the basics, by following the diet and

only take supplements in the doses recommended-- " More is not better " .

Your body is smart enough to balance out all of its nutrient levels, hormones,

water, etc., and become fully oxygenated IF it gets what it needs to do its job

according to Nature's Laws on Health.
