Reference Range. The reference ranges and recommendations in this resource are based on the current, best-available evidence. The reference ranges for hemoglobin (Hb) concentrations in adults are as follows [ 1] : Male: 14-18 g/dL or 8.7-11.2 mmol/L (SI units) Female: 12-16 g/dL or 7.4-9.9 mmol/L (SI units) Pregnant female: >11 g/dL. Laboratory values are expressed in the units used at Each commercial laboratory has its own set of "normal" values, called "Normal Range" or "Reference Range" on your lab report. Normal Adult Laboratory Values. A Comprehensive Guide to Normal Lab Values Laboratory tests are procedures wherein a sample of blood, urine, other bodily fluid or tissue are checked in order to know more about a person’s health. If you have questions about your results, talk to your health care provider. Normal range is 27 to 32 picograms. Several of the normal values for the components of the CBC differ by sex and, therefore, male-specific and female-specific reference intervals are required to interpret these laboratory results. N. mg/dL. Leukocyte count —4000-10,000/μL (4.0-10 × 10 9/ L) Mean corpuscular hemoglobin —28-32 pg.

(more items) A reference range is a set of values that includes upper and lower limits of a lab test based on a group of otherwise healthy people. Each partition group should contain 120 samples. The reference ranges for hemoglobin (Hb) concentrations in adults are as follows [ 1] : Male: 14-18 g/dL or 8.7-11.2 mmol/L (SI units) Female: 12-16 g/dL or 7.4-9.9 mmol/L (SI units) Pregnant female: >11 g/dL. That means that very rarely are you ever going to get exactly the same reference ranges between two or three or five facilities. Hemoglobin electrophoresis is used as a screening test to identify variant and abnormal hemoglobins, including hemoglobin A1 (HbA1), hemoglobin A2 (HbA2), hemoglobin F (HbF; fetal hemoglobin), hemoglobin C (HbC), and hemoglobin S (HbS). 3.5-10.5 x 109/L. Increased risk of developing diabetes in the future (pre-diabetes): A1c of 5.7% to 6.4% (39-46 mmol/mol) For monitoring glucose control, A1c is currently reported as a percentage and, for most people with diabetes, it is recommended that they aim to keep their hemoglobin A1c below 7%. Sex. Normal Range: Female : 11-16 g/dL. Preanalytical factors may also need to be controlled in order to insure that accurate reference ranges … Hemoglobin is often expressed in grams per deciliter (g/dL). The CPT codes provided are based on AMA guidance and are for informational purposes only. Child/adolescent: Newborn: 14-24 g/dL. Red Blood Cells The table revises the most recently published data (Normal Reference Laboratory Values. b) Level II or “Alert” values These are results that deviate from their reference ranges less significantly than Level I values. Montvale, NJ: Thomson PDR; 2007. Synonyms. Hematology Reference Ranges. Please consult your laboratory’s reference values before making clinical decisions. Hemoglobin Reference Range The reference ranges provided here represent a theoretical guideline that should not be used to interpret your test results. Labcorp defines critical (panic) results as laboratory test results that exceed established limit (s) (high or low) as defined by the laboratory for certain analytes as listed in the “Critical (Panic) Limits.” The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes. Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues. Measurement of carboxyhemoglobin and total hemoglobin by five specialized spectrophotometers (co-oximeter) in comparison with reference methods.

To assist physi-cians in treating their pediatric patients, this document lists age-specific reference intervals for many of the endocrine tests offered by LabCorp. Automated Cell Count. Since none of the biomarkers currently available offers perfect validity as a reflection of heavy drinking, considerable research has been undertaken to evaluate using them in combination. They are conventionally set to give the range of values which would be found in approximately 95% of a statistically ‘Normal’ population. Reference ranges are provided as general guidance only. CBC and Automated Differential and Reticulocyte parameters: 1. Interpretation. 6.69 - 7.93 mmol/L. Reference ranges are provided as general guidance only. A reference range data base containing serum chemistry and hematology values on over 3000 animals is described. Elderly: Slight decrease in values. Age-related reference ranges are provided as appropriate, but ranges do not take into account normal racial variation or […] In adults, the average hemoglobin level is slightly higher for men than it is for women. Clinical urine tests are examinations of the physical and chemical properties of urine and its microscopic appearance to aid in medical diagnosis. Regional prevalence in the midwest area of Hb S beta-thalassemia is estimated to be 1:23,000 of the black population. Hemoglobin, Serum. 10.8 - 12.8 g/dL. there are eight different reference ranges and for Hemoglobin even nine reference ranges occur. Theterminology now favored was Typically, this information is provided in the form of a reference interval (RI) or medical decision limit. 11.1 - 14.3 g/dL. Reference ranges are provided as general guidance only. A patient with low levels of hemoglobin has anemia. When evaluating 20 samples, if no more than two results are outside the proposed reference interval range, it is statistically valid for the laboratory to adopt the proposed reference interval as its own. The CPT codes provided are based on AMA guidance and are for informational purposes only. The A1C test is also called the glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C or HbA1c test. CPT coding is the sole responsibility of the billing party. For example, hemoglobin reference ranges should be established by gender and age while cortisol ranges should be subdivided by the time of day. Learn more about laboratory tests, reference ranges, and understanding results. This assay is a quantitative method for measuring the percentage concentration of Hemoglobin A 1C (HbA 1C) in blood.The measurement of Hemoglobin A 1C concentration is recommended for monitoring the long-term blood glucose of persons with diabetes.. Hemoglobin A 1C is formed by the non-enzymatic glycation of the N-terminus of the Beta-chain of Hemoglobin A O. Methods: Different hematoanalyzers were used to examine the white blood cell (WBC), red blood cell (RBC), hemoglobin (Hb), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), and hemotocrit (HCT) of … These values depend on the equipment or method used. Includes: White blood count (WBC), Red Blood Count (RBC) and indices, Hematocrit (HCT), Hemoglobin (HGB) and Platelet Count. Sickle cell anemia is an inherited disorder that leads to the production of an abnormal type of hemoglobin called hemoglobin S (Hb S or Hgb S). Reference Values. PDR Lab Advisor. For example: Laboratory test results are not meaningful by themselves. Frequently, adult reference intervals are not appropriate for pediatric patients. Normal findings [ 1] : 0.06-0.24 g/dL or 9.3-37.2 μmol/L (SI units) 0.4-1.5% of total hemoglobin.
