  1. Results and Result Reporting Skill 304 Dr. Mohammad Marie Lecture \ 6

  2. Learning objectives • To know guidelines in result reporting. • To recognize how to interpret CBC result. • To recognize how to interpret CHEMISTRY result. • To understand the meaning of <critical values>.

  3. Results reporting • Laboratory result consisting of the following • patient identification data • name of lab section • name of test performed • specimen type • lab number • Result may be presented as either of the following: • numerical value • qualitative value • interpretative comments

  4. Results reporting • Reference values should be mentioned in the result report . • Reference range : it is the interval between and including two reference limits ( upper & lower ) for the specific test . • The test should be repeated if the results are out of range

  5. Results reporting • If the sample is rejected, the reasons must be written • Samples may be rejected due to: • Q.N.S sample. (Quantity of specimen not sufficient) • Clotted sample. • Hemolysis sample. • Sample collected in wrong tube. • Teset N/A ( not available ) • Specimen not labeled. • Iincomplete request's information.

  6. Results interpreting CBC

  7. General information Test result Test parameters interpretation Reference range

  8. Results interpreting 1- WBC : white blood cell 2- NEU : neutrophil cell 3- LYM : lymphocyte cell 4- MONO : monocyte cell 5- EOS : eosnophil cell 6- BASO : basophil cell 7- RBC : red blood cell cell 8- HGB : hemoglobin 9- HCT : hematocrit 10-MCV : Mean corpuscular volume

  9. Results interpreting 11- MCH: mean corpuscular hemoglobin 12- MCHC :mean corpuscular hemoglobin conc. 13- RDW : red blood cell distribution width 14- PLT : platelets 15- MPV : Mean platelet volume

  10. Normal ranges

  11. Result interpretation

  12. Results interpreting Chemistry

  13. Results interpreting 1- GLU : glucose 2- UREA OR BUN : Blood urea nitrogen  3- CR-S OR CREA : creatinine 4- URIC : uric acid 5- NA : sodium 6- K : potassium 7- CL : chloride 8- CALC OR Ca : calcium 9- PHS : phosphorus 10- MG : magnesium

  14. Results interpreting 11- FE : ferrous 12- IBCT : total iron binding capacity 13- AST (GOT) : aspartateaminotransferase 14- ALT (GPT) : alaninetransaminase 15- ALP : alkaline phosphatase 16- TBIL : total bilirubin 17- DBIL : direct bilirubin 18- GGT: Gamma-glutamyltransferase 19- TP : total protein 20- ALB : albumin

  15. Results interpreting 21- LIP : lipase 22- AMY : amylase 23- LD : lactate dehydrogenase 24- CK : creatinekinase 25- CK-MB (MBI) : creatinekinase ( M:muscle, B:brain ) 26- CPK : creatinephosphokinase 27- CHOL : cholesterol 28- TG : triglyceride 29- HDL : High-density lipoprotein cholesterol 30- A/G RATIO : albumin/globulin ratio 31- LDL : low-density lipoprotein cholesterol

  16. abbreviations • SE test ( serum electrolyte ) include : NA + K + CL • U/E test include : Urea+electrolyte and mainly include glucose+ creatinine • LFT test ( liver function tests ) include : ALT + AST + ALP + SBR + TP + ALB • RFT or KFT test ( kidney function tests ) include : UREA + CREA

  17. abbreviations • SBR test ( serum bilirubin ) include : TBIL + DBIL • LIPIDE PROFILE test include : CHOL + TG + LDL + HDL • CE test ( cardiac enzyme tests ) include : CK + CKMB + LDH + AST • FULL CHEMISTRY test include : ALL TEST ABOVE

  26. Critical values • Critical Results : a Pathophysiological state at such variances with normal as to be life-threatening unless something is done promptly and for which some corrective action could be taken.

  27. Critical values • PROCEDURE : 1- A critical value result should be confirmed by repeating the test for a second time. 2- If the result is similar to the previous one, the comment code or footnote: CPR (Consistent with the Previous Result) is written by the lab technician. 3- If the result is critical and no history of pervious critical value for this test, the result is confirmed, and the doctor is called.

  28. Some Critical values

  29. Some Critical values

  30. Some Critical values

  31. Some of Critical values • Positive blood culture • Positive CSF (gram stain, culture) • Positive AFB smear (new patient) • Positive smear for P. Falciparum • PositiveMeningococcus (smear or culture) • Positive new MRSA • Positive salmonella or shigella and campylobacter • PositiveClostrediumperfringens • Positive HIV, HEP B , HEP C , CMV • Positive Respiratory Virus (RSV, Adeno, Inf…)
