Are there any discrepancies, variations or controversies relevant to reference ranges for human blood tests?

What are examples of discrepancies, variations or controversies relevant to reference ranges for human blood tests?
Research has revealed that the reference ranges for human blood tests vary from laboratory to laboratory.
This needs to be standardized.

Enzymes and proteins
Hematology red blood cells, white blood cells, coagulation
Immunology; for example, acute phase proteins, isotypes of antibodies, serum free light chains (FLC): kappa/lambda ratio
Ions and trace metals
Liver function
Medication tests; for example, digoxin, lithium, paracetamol
Tumor markers

Arterial Blood Gases

2. Chloride (Cl-)
3. Potassium (K+)
4. Magnesium (Mg++)
5. Calcium (Ca++)
6. Phosphate (HPO4)
7. Bicarbonate (HCO3-)

Enzymes and proteins

Serum total protein
Lactate dehydrogenase (LDH)
Angiotensin-converting enzyme (ACE)
Acid phosphatase
Eosinophil cationic protein (ECP)

Medication tests; for example, digoxin, lithium, paracetamol

What are the causes of elevated urea in human blood test?
Dehydration is the most common cause

What are the causes of elevated creatinine in human blood tests?
Medical biochemistry laboratory error.
Medical biochemistry laboratory reference range variations.
Non-pathological conditions, such as dehydration.
Other similar causes.

Kidney damage is not always the cause of elevated urea or creatinine in human blood tests.

Basic Metabolic Panel

What is the Basic Metabolic Panel blood test for human beings?
A basic metabolic panel (BMP) is a blood test consisting of a set of seven or eight biochemical tests and is one of the most common lab tests ordered by health care providers.

What are other terms for basic metabolic panel blood test for human beings?
The Basic Metabolic Panel is also called Chem 7.

What is included in Basic Metabolic Panel human blood test?
CO2 (carbon dioxide, bicarbonate)
BUN (blood urea nitrogen)

Oxygen saturation can be measured separately by pulse oximetry.

When is this test ordered?
Your provider may order this test during a yearly exam or routine checkup.

What is the difference between basic metabolic panel, comprehensive metabolic panel and metabolic panel 20 in human blood tests?
8 components are measured in basic metabolic panel.
14 components are measured in comprehensive metabolic panel.
20 components are measured in Chem 20 metabolic panel.

What is included in the comprehensive metabolic panel human blood test?
Albumin: 3.4 to 5.4 g/dL
Alkaline phosphatase: 44 to 147 IU/L
ALT (alanine aminotransferase): 10 to 40 IU/L
AST (aspartate aminotransferase): 10 to 34 IU/L
BUN (blood urea nitrogen): 6 to 20 mg/dL
Calcium: 8.5 to 10.2 mg/dL
