## Your results page, translated

Your doctor ordered a blood panel and the results landed in your inbox. The page shows two columns of numbers, each with a "reference range" printed beside it, and flags on anything outside it. Most people spend twenty minutes Googling each item separately, landing on a different ad-heavy site per marker. This page is the one-stop version: all three panels that appear on a standard annual check-up (complete blood count, metabolic panel, lipid panel) in one place, with the range, the unit, and plain-language notes on what high and low usually indicate. It is a reading aid, not a diagnosis. Your own lab's reference range (printed on your results) is always the number to judge against, since ranges vary slightly by analyser and population.

## Complete blood count (CBC): what it measures

The CBC counts the cells circulating in your blood. It has three main groups: red cells (which carry oxygen), white cells (which fight infection), and platelets (which seal wounds). A CBC is ordered for almost every annual check-up, every hospital admission, and any time a doctor wants a quick picture of overall health. The six markers below appear on virtually every standard CBC report.

## CBC: Complete Blood Count

Marker

Range (adults)

High usually means

Low usually means

WBC (white blood cells)

4,500 to 11,000 /mcL

Infection, inflammation, or rarely leukaemia

Bone marrow suppression or immune disorder

RBC (red blood cells)

M: 4.6 to 6.2 M/mcL, F: 4.2 to 5.4 M/mcL

Polycythaemia or chronic low oxygen

Anaemia from blood loss or deficiency

Haemoglobin

M: 13 to 18 g/dL, F: 12 to 16 g/dL

Dehydration or polycythaemia

Anaemia reducing oxygen delivery

Haematocrit

M: 40 to 55 %, F: 36 to 48 %

Dehydration or excess red cells

Anaemia or severe blood loss

MCV (mean corpuscular volume)

80 to 100 fL

Macrocytic anaemia, B12 or folate deficiency

Microcytic anaemia or iron deficiency

Platelets

150,000 to 400,000 /mcL

Reactive thrombocytosis or bone marrow disorder

Bleeding tendency or bone marrow failure

## Metabolic panel (CMP or BMP): what it measures

The comprehensive metabolic panel (CMP) checks how your kidneys, liver, and electrolytes are doing in one draw. A basic metabolic panel (BMP) is the same without the liver markers. The 11 markers below cover everything in a standard CMP. Glucose should be fasting (8 hours without food) for the most useful reading. All other markers are unaffected by fasting.

## CMP: Metabolic Panel

Marker

Range (adults, fasting)

High usually means

Low usually means

Glucose

70 to 100 mg/dL

Diabetes or impaired glucose control

Hypoglycaemia (shakiness, confusion)

BUN (blood urea nitrogen)

6 to 20 mg/dL

Kidney dysfunction or dehydration

Liver disease or malnutrition

Creatinine

M: 0.7 to 1.3 mg/dL, F: 0.5 to 1.1 mg/dL

Kidney disease or muscle breakdown

Low muscle mass or severe liver disease

Sodium

135 to 145 mEq/L

Dehydration or kidney disease

Overhydration or adrenal insufficiency

Potassium

3.5 to 5.0 mEq/L

Kidney disease or excess supplementation

Heart arrhythmias or muscle weakness

Calcium

8.5 to 10.5 mg/dL

Hyperparathyroidism or bone disease

Vitamin D deficiency or hypoparathyroidism

ALT (alanine aminotransferase)

7 to 56 U/L

Liver damage, hepatitis, or fatty liver

Rarely clinically significant

AST (aspartate aminotransferase)

10 to 40 U/L

Liver injury or muscle breakdown

Rarely clinically significant

Alkaline phosphatase

44 to 147 U/L

Liver obstruction or bone disease

Malnutrition or hypothyroidism

Total bilirubin

0.1 to 1.2 mg/dL

Liver disease or red cell breakdown

Rare; not usually flagged

Albumin

3.5 to 5.0 g/dL

Dehydration

Liver disease or malnutrition

## Lipid panel: what it measures

A lipid panel measures the fats in your blood that relate to cardiovascular risk. It is almost always ordered fasting (12 hours without food), because triglycerides spike dramatically after a meal. The four markers below appear on every standard lipid panel. Note that for HDL, higher is protective: a low HDL raises cardiovascular risk even if total cholesterol looks fine.

## Lipid Panel

Marker

Range (adults, fasting)

High usually means

Low usually means

Total cholesterol

Below 200 mg/dL (desirable)

Elevated cardiovascular risk

Severe malnutrition or liver disease (rare)

LDL cholesterol

Below 100 mg/dL (optimal)

Plaque build-up risk in arteries

Rare genetic disorder or malnutrition

HDL cholesterol

M: above 40 mg/dL, F: above 50 mg/dL

Protective effect against heart disease

Increased cardiovascular risk

Triglycerides

Below 150 mg/dL

Metabolic syndrome, diabetes, or diet

Malnutrition (uncommon finding)

Four things that shift your numbers before a flag means anything. First, hydration: even mild dehydration concentrates the blood and raises haematocrit, haemoglobin, albumin, and creatinine. Drink normally the morning of your draw. Second, timing: strenuous exercise in the 24 hours before a draw elevates AST, creatinine, and CK (if ordered). Third, fasting: glucose and triglycerides are only meaningful fasting. Fourth, lab variation: each analyser is calibrated to its own population, so a value
