URIT-12 Hemoglobin Meter
Operating Manual
For in vitro diagnostic use
Chapter One: Introduction
URIT-12 Hemoglobin Meter is designed for use only with H12 Hemoglobin Test Strip from URIT Medical Electronic
Co., Ltd, for the quantitative measurement of total hemoglobin in capillary and venous whole blood.
Hemoglobin is the oxygen-carrying protein in red blood cells. The quantitative measurement of hemoglobin is indicated
and clinically useful in acute illness as well as in general care. The normal range hemoglobin values reported in medical
literature are gender and age dependent:
Adult males 13.5 ~ 18.0 g/dL
Adult females 12.0 ~16.0 g/dL
Infants Ranging from 14.5 ~ 22.5g/dL after birth to 11.1 ~14.1g/dLat 6 months old.
Children Gradually increase from infant to adult levels.
Low hemoglobin levels may indicate condition such as anemia or hemorrhage. Elevated hemoglobin levels may indicate
conditions such as polycythemia. A hemoglobin test may be used as part of a general screen for many types of patient
populations, including the elderly, children, and women of child-bearing age, and prior to giving or receiving
transfusions. Due to differences among patient populations, we recommend that each clinical site establish its own
reference ranges.
People use Hemoglobin Meter with the whole blood for local inspection or tending, which is helpful for evaluating
patients’ symptom quickly and providing proper treatment determination.
When test result is different from clinical symptom, repeat test. If there are still some problems, validate it by control or
compare hemoglobin test methods with that of other labs.
Judge the clinical signification of test result by following the doctor’s direction. Prior to any medication, treatment
should be provided by doctor based on test result and clinical symptom.

Chapter Three: Principal of Operation
The hemoglobin meter utilizes optical reflectance for determination of the total hemoglobin. The test strip is inserted into
the meter when prompted, a background blank reading is automatically determined. A drop of whole blood is applied to
the test spot on the strip, blood immediately disperses within the membrane, contacting the reagent, then reaction product
could absorb spectrum in the range of 500nm-600nm.The meter’s optical detector automatically measure the change in
membrane reflectance. The intensity of reflectance is inversely proportional to the hemoglobin concentration. The meter
calculates and displays the total hemoglobin concentration in gram/deciliter (g/dL) in 30 seconds based on a
mathematical conversion.
Chapter Four: Blood Sample Collection
1. Fresh capillary or EDTA-anticoagulated venous whole blood may be used.
2. If an EDTA-treated sample is refrigerated, allow it to come to room temperature prior to use. EDTA-treated blood
samples should be mixed using end to end inversions at least 8 times prior to use, and should be tested within 24 hours.
3. For fresh venous whole blood samples, collect approximately 0.1mL into an anticoagulant-free plastic syringe.
Chapter Five: Note
1. URIT-12 Hemoglobin Meter is for in vitro diagnostic use only.
2. URIT-12 Hemoglobin Meter is designed for use only with H12 Hemoglobin Test Strips from URIT Medical
Electronic Co., Ltd. Prior to the first use of test strips, read the Manual carefully and input the Lot Code to the meter.
3. Insufficient blood sample volume and inadequate mixing of EDTA-treated samples may affect results.
4. As all diagnostic tests, test results should be evaluated according to the specific patient’s condition. Any results
demonstrating the inconsistency with the patient’s clinical status should be repeated or supplemented with additional test
data.
5. In order to test the hemoglobin accurately, please use and maintain the meter correctly. Review this manual prior to
the first use of the meter.
6. While the test is in progress, do not disturb or move the meter or strip, even press any key.
