Appendix B
commentS on reporting of teSt reSultS
The technician must know the normal or reference value of the test. A list of these values is
given in this appendix. One should bear in mind that the normal values and reference range
may vary from laboratory to laboratory as well as on the methodology used. The method of
specimen collection may also inuence these results. The laboratory must specify its own
normal ranges.
The technician should have the knowledge to recognize abnormal test results and its trend.
Just geing some numerical gures without a meaningful conclusion is wasteful. Abnormal
test paerns or trends can sometimes provide more useful information than single test
outcome deviations. Conversely, single test results can be normal in patients with a proven
disease or illness. While studying the result one must take into consideration the biocultural
normal variation. Thus low haemoglobin level in Asiatic Indians and high haemoglobin
concentration in Mexican Americans are common observations.
Panic test results must be immediately communicated to the physician. Time-critical
information is of limited value if it is delayed or not received. Even though computerized
communication technologies contribute to faster information delivery, clinicians are oen le
waiting for crucial laboratory data. The wireless networks can expedite the reporting of vital
patient data to the health care provider so that treatment can begin without delay.

Appendices
1289
Medical laboratory personnel must be able to recognize margins of error. For example, if a
patient has a baery of chemistry tests, the possibility exists that some tests will be abnormal
owing purely to chance. This occurs because a signicant margin of error arises from the
arbitrary seing of limits. Thus if the patient has a group of tests performed on one blood
sample, the possibility that some of the tests will “read abnormal” due purely to chance is
not uncommon.
normAl VAlueS (lABorAtory reference VAlueS)
While referring to the normal or laboratory reference values, one should bear in mind that
they vary from laboratory to laboratory, dierent populations and the methodology used.
The laboratory must specify its own normal ranges.

Preparation of Phosphate Buffers
Phosphate buers are generally used, since the pH range of the mixtures is from 5 to 8.
Reagents
A. Monobasic potassium phosphate (0.066 M)
Dissolve 9.0727 g of KH2PO4 in distilled water and dilute to 1000 mL in a volumetric ask. The
solution must be absolutely clear and should yield no test for chloride or sulphates (Chapter
4 of Vol. 1). Keep the solution in refrigerator.
B. Dibasic sodium phosphate (0.066 M)
Dissolve 11.867 g of Na2HPO4.2H2O in distilled water and dilute to 1000 mL in a volumetric
ask. (Note If the dibasic sodium phosphate has 12 moles of water of crystallization, expose
the salt to ordinary atmosphere for two weeks; it will then contain 2 moles of water of
crystallization.) The solution should be absolutely clear and free from chloride or sulphates.
Keep in the refrigerator.
Procedure
Mix the solutions (A) and (B) in the following proportions in order to obtain the desired pH.
