Here is a complete, easy-to-use guide for reading blood sugar and blood pressure values in hospital reports.

Blood Sugar (Glucose) Values - Hospital Report Guide

1. Fasting Plasma Glucose (FPG)

Taken after at least 8 hours of fasting.

Category	Fasting Glucose (mg/dL)
Normal	70 - 99 mg/dL
Prediabetes (Impaired Fasting Glucose)	100 - 125 mg/dL
Diabetes	≥ 126 mg/dL

2. Random (Non-Fasting) Plasma Glucose

Taken at any time, regardless of meals.

Result	Meaning
< 140 mg/dL	Normal
140 - 199 mg/dL	Impaired (possible prediabetes)
≥ 200 mg/dL + symptoms	Diagnostic of Diabetes

3. 2-Hour Oral Glucose Tolerance Test (OGTT)

Blood is drawn 2 hours after drinking a 75g glucose solution.

Category	2-hr Result (mg/dL)
Normal	< 140 mg/dL
Prediabetes (Impaired Glucose Tolerance)	140 - 199 mg/dL
Diabetes	≥ 200 mg/dL

4. HbA1c (Glycosylated Hemoglobin / Hemoglobin A1c)

Reflects average blood sugar over the past 2-3 months. Very commonly seen in hospital reports.

Category	HbA1c %
Normal	< 5.7% (some labs: 4-6%)
Prediabetes	5.7% - 6.4%
Diabetes Diagnosed	≥ 6.5%
Well-controlled diabetes (treatment goal)	< 7.0%
Poorly controlled diabetes	10% - 12% or above

Blood Pressure (Hypertension) Values - Hospital Report Guide

According to the ACC/AHA classification (used in Harrison's Principles of Internal Medicine 22E):

BP Category	Systolic (mmHg)		Diastolic (mmHg)
Normal	< 120	and	< 80
Elevated	120 - 129	and	< 80
Stage 1 Hypertension	130 - 139	or	80 - 89
Stage 2 Hypertension	≥ 140	or	≥ 90
Hypertensive Crisis	> 180	and/or	> 120

Important: When systolic and diastolic readings fall in different categories, always use the higher classification.

Older JNC Classification (still seen in some reports):

Category	Systolic		Diastolic
Normal	< 120	and	< 80
Prehypertension	120-139	or	80-89
Stage 1 HTN	140-159	or	90-99
Stage 2 HTN	≥ 160	or	≥ 100

Other Common Terms on Hospital Reports

Term	What It Means
FBS / FPG	Fasting Blood Sugar / Fasting Plasma Glucose
RBS / RBG	Random Blood Sugar / Random Blood Glucose
PPBS	Post-Prandial Blood Sugar (2 hours after eating)
HbA1c / A1c	3-month blood sugar average
OGTT	Oral Glucose Tolerance Test
SBP	Systolic Blood Pressure (top number)
DBP	Diastolic Blood Pressure (bottom number)
BP: 130/85	SBP = 130, DBP = 85 - Stage 1 HTN
mmHg	Millimeters of mercury - unit for blood pressure
mg/dL	Milligrams per deciliter - unit for blood glucose

Quick Summary Card

BLOOD SUGAR
  Normal fasting:    70–99 mg/dL
  Prediabetes:      100–125 mg/dL (fasting)
  Diabetes:         ≥126 mg/dL (fasting) or ≥200 mg/dL (random with symptoms)
  HbA1c Normal:     < 5.7%
  HbA1c Prediabetes: 5.7–6.4%
  HbA1c Diabetes:   ≥ 6.5%
  HbA1c Goal (treated): < 7.0%

BLOOD PRESSURE
  Normal:           <120/<80
  Elevated:         120–129/<80
  Stage 1 HTN:      130–139 / 80–89
  Stage 2 HTN:      ≥140 / ≥90
  Crisis:           >180 / >120

Key Tips for Reading Hospital Reports:

Blood sugar values must always be interpreted alongside whether the patient was fasting or not
A single high reading is not always diagnostic - diabetes typically requires two abnormal readings on different days (unless symptoms are present with glucose ≥200)
Blood pressure should be an average of 2+ readings on 2+ separate visits
HbA1c is the most reliable overall indicator and does not require fasting

Here is a complete guide to all minerals and their normal values in blood/serum, as used in hospital reports. Sources: ABIM Laboratory Reference Ranges (Jan 2026) and NBME Laboratory Values.

All Minerals - Normal Reference Values (Hospital Reports)

MAJOR ELECTROLYTES (Macrominerals)

Mineral	Test Name	Normal Range	SI Units
Sodium (Na+)	Serum Sodium	136-145 mEq/L	136-145 mmol/L
Potassium (K+)	Serum Potassium	3.5-5.0 mEq/L	3.5-5.0 mmol/L
Chloride (Cl-)	Serum Chloride	98-106 mEq/L	98-106 mmol/L
Bicarbonate (HCO3-)	Serum Bicarbonate	22-28 mEq/L	22-28 mmol/L

BONE & MUSCLE MINERALS

Mineral	Test Name	Normal Range	SI Units
Calcium (Ca2+)	Serum Calcium (total)	8.4-10.2 mg/dL	2.1-2.6 mmol/L

Tips for reading mineral values in hospital reports:

Values vary slightly between labs - always check the reference range printed on your report
"mEq/L" and "mmol/L" are the same for sodium, potassium, chloride, and bicarbonate (they are 1:1)
"mg/dL" is used for calcium, magnesium, and phosphorus
"µg/dL" is used for iron, zinc, copper (microgram = very small amount)
Ferritin is the best single test for iron stores; iron alone can be normal even when stores are depleted
