Whenever there is a patient admitted to the hospital, there are always routine examinations that the patient should undergo to provide the baseline data needed by the physicians to commence treatment. Some patients are subjected to laboratory examinations for the proper detection and screening of their conditions. The normal lab values chart is important for the health care providers because it helps them determine whether the results are normal or if there are abnormalities.

The following are the normal lab values chart for some of the common tests performed for screening or diagnosis.

Normal lab values chart for complete blood count

Complete blood count (CBC) is the test that measures the amount of red blood cells, white blood cells, platelets and other components of the blood.The CBC can aid the health care provider as well as the patient to check the status of the formed elements in the blood.

Blood components Normal value
Red blood cells 4- 6 M/ µL
Hemoglobin (male) 14- 18 g/ dL
Hemoglobin (female) 12- 16 g/ dL
Hematocrit (male) 39- 54 %
Hematocrit (female) 34- 47%
Mean corpuscular volume (MCV) 78 – 98 fL
Mean corpuscular hemoglobin (MCH) 27 – 35 pg
Mean corpuscular hemoglobin concentration (MCHC) 31 – 37%
White blood cells 5000- 10000 mm³
Basophils 0 – 1%
Eosinophils 1-5%
Neutrophils 50 – 81%
Lymphocytes 14- 44%
Monocytes 2-6%

Normal lab values chart for Electrolytes

Electrolytes are needed by the body because they serve to keep it in astate of equilibrium. Electrolytes help the cells, brain, nerves and muscles to function effectively and also control the level of water in the body.

Electrolytes Normal values
Sodium 135 – 145 mEq/L
Potassium 3.5 – 5.5 mEq/L
Phosphorous 2.2 – 4.8 mg/dL
Magnesium 1.5 – 2.5 mg/dL
Iron 52 – 169 µg/dL
Chloride 96 – 112 mEq/L
Calcium 8 – 11 mg/dL

Normal lab values chart for blood coagulation

When a patient is given warfarin and heparin medications, he or she is observed for signs of bleeding.The normal lab values chart for blood coagulation is referred to for any signs of improvement or complications happening with the patient.

Normal values
Platelets 140,000 – 450,000 / ml
Prothrombin time (for warfarin medication) 11 – 16 seconds
Activated Partial Thromboplastin Time (for heparin medication) 30 – 45 seconds
Fibrinogen 160 – 450 mg/dL
Bleeding Time 3 – 9 minutes
Thrombin time 11 – 15 seconds
Plasminogen 62 – 130%

Normal lab values chart for cardiac markers

Cardiac markers are important indicators for patients at risk of myocardial infarction. Seeing the lab values chart for the normal ranges of the cardiac markers would assist the health care provider in determining if there is any danger of myocardial infarction.

Cardiac Markers Normal Values
Troponin I 0 – 0.1 ng/ml

onset: 4-6 hours

peak: 12-24 hours

returns to normal: 4-7 days

Troponin T 0 – 0.2 ng/ml

onset: 3-4 hrs

peak: 10-24 hrs

returns to normal: 10-14 days

Creatinine Kinase-MB (CK-MB) Males: 50- 325 mu/ml

Females: 50- 250 mu/ ml

Onset: 3- 6 hours

Peak: 12- 18 hours

Returns to normal: 3-4 days

Myoglobin 10 – 95 ng/ml

onset: 1-3 hours

peak: 6-10 hours

returns to normal: 12-24 hrs

Lactic Dehydrogenase 100- 225 mU/ml

onset: 12 hours

peak: 48 hours

returns to normal: 10- 14 days

Aspartase Aminotransferase (AST) 7- 40 mu/ml

Onset: 4- 6 hours

Peak: 24- 36 hours

Returns to normal: 4 to 7 days

Normal lab values chart for urine

One of the important outputs of the body is urine. Urine can aid us in finding out how well the kidneys are working.Urine test or urinalysis is also one of the most common laboratory tests ordered by doctors as part of the diagnostic procedures for many illnesses. The normal lab values chart for urine is crucial in interpreting the results and making a diagnosis.

Normal Values
color Clear to straw color
Specific gravity 1.003 – 1.040
pH 4.6 – 8.0
Creatinine 1 – 2 g / 24 hr
Creatine Clearance (Male) 100 – 140 mL / min
Creatine Clearance (Female) 80 – 130 mL / min
Osmolality 80 – 1300 mOsm/L
Protein 1 – 15 mg/dl
BUN 6- 23 mg/dl

The normal lab values chart does help both the physician and the patientin identifying if the condition is considered normal or not; however, the normal lab values chart can have variations from one laboratory to another. The best thing to do to avoid misinterpretations of the results is to check the standards of the laboratory where the test was conducted. The health care provider must know that the result of the laboratory examination is not the sole diagnostic factor required to confirm the condition of the patient.
