Ferritin

On May 11, 2010, in Minerals, Tests, by Andrea

Ferritin is another iron blood test used to determine iron stores.  It is used in conjunction with additional  iron tests to determine overall iron status, as well as supplement efficacy.

Over time, ferritin levels can show how well the body is storing iron, and utilizing that iron.  It is a useful tool, especially when looking at trends.

Ranges given are simply given as a point of reference.  Your lab may use slightly different lab values.  Adapt as necessary.

This is a fasting test.  Mornings are best.

Osteocalcin

On May 10, 2010, in Minerals, Tests, by Andrea

Osteocalcin is one of those strange labs that we recommend that no one seems to know what it is — including, I think, some of the docs that may or may not actually order it.

Because it is one of the more obscure labs, many docs will not actually run it for you, but let’s go over it to explain what it is, why it’s important, and why it’s gaining ground in the lab-work field.

Remember that ranges are just that — ranges.  Nothing is set in stone, and each lab sets their own range.  Your mileage may vary.

This is a fasting test.

Iron, TIBC, and Iron Sat %

On May 7, 2010, in Minerals, Tests, by Andrea

It seems people really have trouble understanding iron.  I get it — iron is confusing all to hell.  There’s lots of things that I look at when I am evaluating iron status.  I look at things from the CBC (HCT, HGB, MCH, MCHC, RDW), things from a Hemogram, things from the TIBC, and a Ferritin level.  Sometimes?  I even look at a protein score.  So yes, very, very confusing.

Ranges given are simply given as a point of reference from MY laboratory.  Your lab may use slightly different lab values.  Adapt as necessary.

Many labs consider this a fasting test – but not all.  At the very least, it is best drawn in the morning.

Comprehensive Metabolic Profile

On April 27, 2010, in Tests, by Andrea

The CMP, or comprehensive metabolic panel, is a series of 14 blood tests which is a pretty routine draw for annual physicals or check-ups.  Over time, it can show some important baselines for basic physiology and can show how WLS changes our physiology in the long-term.  Any changes or abnormal results can direct a physician to order more specific tests.  The CMP provides basic information on kidney function, liver function, and electrolyte and fluid balance.  It is also used to monitor patients of chronic disease such as diabetes or hypertension.

Ranges given are simply given as a point of reference from MY laboratory.  Your lab may use slightly different lab values.  Adapt as necessary.

This is a fasting test.

The following tests are performed as part of the CMP:
