Type of Blood Tests
- Torniquet Test (Capillary Fragility Test)
- Bleeding Time (Ivy Method)
- Platelet Count (Direct Method; Rees-Ecker)
- PT (Prothrombin Time)
- APTT (Activated Partial Thromboplastin Time)
HSC 2011 Batch
- Prothrombin Time is used to measure: Factor X. (Also Factors II, V, and VII).
- The function of sodium citrate: calcium binding.
- Normal platelet count: 150,000-400,000/ml.
- Petechiae considered positive if: more than 20.
- Instrument that cannot gauge bleeding time: stethoscope.
- Conditions that can cause positive petechiae: Thrombocytopenia, fibrinogen deficiency, vascular purpura.
- Which is not a function of torniquete exam: to check for anemia.
- Rumple Leede test is used to check for: Dengue fever.
- Platelets are seen from: 20 Field of View.
- Centrifuge speed: 3000 rpm.
- Normal time to bleeding time is: 1-6 minutes.
Batch 2011 International Program
- Mention 3 substances which constitute Ress-Ecker solution: Sodium citrate, brilliant cresyl blue, formaldehyde 40%
- Torniquet test (+)1 and (+)4 can be interpreted as:
- +(1): A few petechiae on the anterior forearm.
- +(4): Confluent (over-lapping) petechiae on the arm and back of the hand.
- The following equipment is required for aPTT test, except: microscope.
- A doctor is about to perform torniquet test on a 22 year old patient with BP 140/80. Which one of the following is the appropriate cuff pressure to be applied to the patient in order to get reliable test result: 100 mmHg.
- What is the cut-off point for sum of petechiae per inch squared to interpret torniquet test results as positive: 20.
- Platelet count in thin blood smear is done by counting the sum of platelet in 20 immersion view.
- Which one of these coagulation factor's level affect both PT and aPTT test result: Factor X.
- Tissue Factor is required in intrinsic pathway of coagulation cascade. False.
- Normal PT result and abnormal aPTT result is found in patients with severe hypocalcemia. T/F.
- If the sum of platelet in 2 large squares is 300 platelets, then the sample's platelet level is normal. T/F.
Group 5 from the 2011 batch (and possibly other groups) were asked to write about Idiopathic Thrombocytopenic Purpura in the Clinical Correlation section of their lab report.
