Glucose Levels Chart (Normal blood sugar levels target charts)

How to read your blood glucose results and how to interpret glucose levels using simple and easy sugar chart for all ages and conditions, below is blood glucose level map in mmol/l unit (used in uk) and determined values in mg/dl unit (used in USA, Canada, and world wide). here is what should your blood sugar level be.

I’ve seen many questions out there such as:
What is normal blood sugar level for adults man or woman, are kids sugar levels chart different than old person sugar, what is the standard glucose value to adjust my sugar level, have my glucose treatment succeeded, do I still in danger of high glucose values?, blood glucose levels for non fasting males and females?, What is the blood sugar range for a non diabetic person?, are morning blood sugar levels is diabetes or non diabetic?, what is safe sugar level during pregnancy?, Do glucose in blood rise after eating or be normal? How bad is my blood glucose level?
And others like that, just follow my guideline
Estimate your sugar level in the lab
After receiving lab work results, just look to your lab report and save in your mind the numbers typed right in front of test name called one of these:
Blood Glucose (no common and usually preceded by type of sample as following below)
Serum Glucose (“serum or blood” in medical reports for glucose test may be used as synonymous, also S. before the test name means “serum” and Bl. for “blood”)
Random blood glucose (Levels of sugar in the blood of a person at ant time of the day except fasting)
Fasting Blood Glucose (sugar level in patient’s blood after fasting from 6 -8 hours or overnight fasting)
2h Postprandial Glucose (estimating how sugar reaches its level in blood two hours after eating a usual meal)

Identifying a glucose range in sugar levels table
Print that glucose levels table or fix screen to make it in front of your eyes
Do not look around, just keep your focus on the figures in the report and compare it to the level ranges sorted in the sugar chart.

Describe you diabetic condition
Once you find a corresponding glucose range to your level in the glucose test results, then by now you’ve found what your sugar levels are whether you have a normal sugar or abnormal levels or whatever it be, it going to describe your diabetic status, I mean are you diabetic or non-diabetic, if diabetic how to control diabetes level to reach the normal blood sugar figures, if non-diabetic then everything is great.

Know the exact steps to do in each situation to be reassured
Set control blood sugar levels during Diabetes, pregnancy, childhood, and for every type of diabetes mellitus.

Type1,2 Blood Sugar levels chart in mg/dl and mmol/L Vs urine glucose amounts
mg/dl mmol/L urine Glucose Interpretation
1000 55.56 +++++ Rare but possible, ridiculously high sugar in alive person, long period in that level lead to death
700 38.89 +++++ 700 or higher is possible, unless the patient admitted it will be among the dead
600 33.33 +++++ High mortality rates and passing out for a long time (coma),
500 27.78 ++++ Critical Value with seriuos complications which requires fast medical desician
400 22.22 +++ Dangerous blood sugar levels chart starts in counting, immediate sugar control is must
300 16.67 ++ Uncontrolled diabetes mellitus, HBA1c test is required to start medication course
200 11.11 + Diagnostic glucose level, person with random blood sugar 200 mg/dl is called “Diabetes”
180 10.00 +/trace high glucose value for RBG test and control level for children type 1 DM
162 9.00 trace/nill Target Postprandial sugar level for type 1
153 8.50 trace/nill Target 2hpp sugar Level for Type 2 diabetes mellitus
150 8.33 nill Normal glucose results for Random non fasting sugar measurement
144 8.00 nill Fasting children type1 upper sugar level
140 7.78 nill upper limit of normal random blood glucose results
126 7.00 nill Diagnostic fasting blood sugar is 126 mg/dl and higher, entry level to diabetes
125 6.94 nill Upper Normal glucose limit allowed for fasting
110 6.11 nill At fasting suggests Prediabetic and impairment of glucose or DM person need more control
108 6.00 nill After 6 – 8 hours fasting sample is Prediabetic suggestive
107 5.94 nill Acceptable range, Person is non-diabetic still in normal range of sugar in blood
100 5.56 nill Excellent Normal sugar level for healthy people or a person have tightly controlled his sugar level
72 4.00 nill Lowest acceptable sugar level for random and fasting test, & doctor target for successful diabetes control
70 3.89 nill Fair Hypoglycemia starts which means abnormal low sugar in blood
50 2.78 nill Hypoglycemic person common signs and A higher heart rate than usual,  coma is possible
30 1.67 nill Critical low sugar level and very dangerous drop level coma can occur, fast hospitalization is must
10 0.56 nill Clinically alive person sugar shouldn’t declined to that level

Some Diabetes testing definitions
RBG is for Random Blood Glucose test, taken anytime between meals, included in non fasting blood sugar levels chart, also called routine sugar measurement however RBG test is a component of routine medical check up panel.
FBG is for Fasting Blood Glucose test, optimal 6 – 8 hrs after last meal or measured morning right out of bed, Read more about fasting blood sugar levels
2hPPG is for 2 Hrs Postprandial Glucose test
Normal Level means sugar measurement in the blood is within healthy standard values
Target level means required sugar levels to say that diabetic control succeeded
Critical value is the most dangerous blood sugar level which harms many other body organs and requires fast clinical hospitalization
Hyperglycemia means high blood glucose results
Hypoglycemia means low blood glucose results
Type 1 Diabetes mellitus is a medical condition due to insulin insufficiency
Type 2 Diabetes mellitus is a medical condition where body cells do not receive glucose due to reasons not related to insulin hormone production.
Adults have either type 1 diabetes or type 2 diabetes, while Children usually have type 1 diabetes

Glucosuria or Glycosuria is a condition when blood glucose amount overflow into urine, seen after blood level exceeds160 – 180 mg/dl, and affected by renal glucose threshold.
Ketonuria is a condition when Ketone molecules appear in urinalysis due to diabetes or starvation or long hospitalization.

Target sugar levels table interpretation
Target level is the normal blood sugar levels a patient must adjust his/her glucose level to it.
Normal level means the glucose levels which restored naturally by the body regulation.
Note that after meal there is what called insulin shot which cause glucose to rise ‎temporarily to 140 mg/dl or 7.8 mmol/L ‎

Target normal glucose ranges map by Diabetes type in mg/dl

Random glucose  Fasting glucose  2hpp glucose 
Normal Healthy 72 – 150 72 – 100 72 – 140
Type 1 DM Preferred FBG 72 – 126 under 162
Type 2 DM Preferred FBG 72 – 126 under 153
Gestational diabetes GTT is Preferred 72 – 126 under 140
Children type 1 DM FBG more diagnostic 72 – 144 under 180
Sugar levels table for common diagnostic ranges
500 – 1000 Very serious sugar levels, longer period than some minutes without fast hospital admission means death.
108 – 126 Prediabetic level which suggests glucose impairment glycemia
72 – 125 Target blood sugar level for type 1, 2, for fasting test
72 – 144 Target type 1 DM for children for fasting test
30 – 70 Severe Hypoglycemia
After we’ve shown expected high blood sugar levels chart, lets know the low sugar levels
Hypoglycemia chart
Hypoglycemia is the case commonly affect alcoholic persons and patients take insulin overdose, also high body demand or low energy source cause body to be hypoglycemic.
Hypoglycemia means that blood sugar level falls below 72 mg/dl or 4.0 mmol/L when sugar test is taken.
low blood sugar chart is simple compared to high sugar level chart
Serious low sugar level is under 50 mg/dl,
Critical sugar hypoglycemia level is 30 mg/dl it may be the death degree sugar level which need urgent medical decision.
Hypoglycemic person common sign is Sweating, Fatigue, Feeling dizzy, Feeling hungry, A higher heart rate than usual, confusion, and in extreme cases can develop coma and/or other complication as:
Cognitive decline
Impact on brain power
Dead in bed syndrome
Weight gain
Chart interpretation:
Target Glucose Levels for Type 2 diabetes mellitus
Fasting glucose level should lies among 72 – 126 mg/dl (equivalent to 4 to 7 mmol/L)
‎2 hours after meal‎ blood sugar level should be under 153 mg/dl (corresponding to 8.5 mmol/L)Target Glucose Levels for Type 1 diabetes mellitus
Fasting sugar levels 72 – 126 mg/dl (4 – 7 mol/L)
Postprandial sugar level should be any figure less than 162 mg/dl (9.0 mmol/L)
Target Glucose Level for Children type 1 DM
Children diabetic level is a bit higher than adults by 1 mmol/L
Normal desirable blood glucose level is from 72 to 144 mg/dl (or 4 – 8 mmol/L) for fasting sugar test, i.e. pre-prandial.
180 mg/dl (10 mmol/L) is the normal sugar level must not exceed for 2hPP Glucose test.
Gestational diabetes:
A condition occurred to pregnant women due to many reasons some of them related to placental enzymes and others related to kidney problems, for pregnant female diabetes condition called transient diabetes insipidus or fake diabetes and  controlled during pregnancy course to not harm fetus or transform to diabetes 2 after years of birth.
Dangerous blood sugar levels chart interpretation  
500 is the upper critical high glucose degree (critical hyperglycemic value) for adults and children males and females which can appear in random glucose results.
50 is the lower critical hypoglycemic value seen in both fasting and non-fasting glucose test results for all ages.

Prolonged 200 or higher is very serious and cause damage to kidney and body tissues
