Differences between clotting and bleeding time

-
Clotting Time vs Bleeding Time
Clotting Time
- Measures: Time it takes for blood to clot in a test tube.
- Assesses: Coagulation cascade function.
- Tests: Intrinsic and extrinsic clotting pathways.
- Examples: Activated partial thromboplastin time (aPTT), prothrombin time (PT).

Bleeding Time
- Measures: Time it takes for bleeding to stop after a standardized cut or puncture wound.
- Assesses: Platelet function and primary hemostasis.
- Tests: Ability of platelets to form a platelet plug.

Key Differences
- Mechanism: Clotting time evaluates coagulation factors, while bleeding time assesses platelet function and vascular response.
- Method: Clotting time is measured in vitro (in a test tube), while bleeding time is measured in vivo (in the body).

Both tests provide valuable information about hemostasis and can help diagnose bleeding disorders.

Body of Ebola victim cremated in Lagos

-
The body of the first victim of Ebola Virus Disease in Nigeria, who died in Lagos on Friday, has been cremated. Details of the cremation were not available at press time but Sunday Vanguard gathered that the event was witnessed by officials of the Lagos State Ministry of Health and the Nigeria Centre for Disease Control, NCDC, led by its Project Director, Professor Abdulsalam Nasidi, among others. The decision to cremate the body of the victim, it was further gathered, may not be unconnected with the deadly nature of the Ebola Virus which is known to be easily transmissible from human to human during handling of corpses of victims. The World Health Organisation recommends that in communities where there is an outbreak of Ebola, appropriate containment measures including burial of the dead should be properly handled. While stating that people who die from Ebola should be promptly and safely buried, WHO notes that cremation, which is the application of high temperature to reduce b...

World football governing body FIFA have withdrawn bronze boot award from Golden Eaglets skipper Kelechi Nwakali at the recent U17 World Cup in Chile and re-awarded it to compatriot Samuel Chukwueze after a mistake In a letter to the NFF general secretary, Mohammed Sanusi, and signed by Mustapha Fahmy, director of the football division, FIFA admitted their blunder: “We made a mistake at the closing ceremony of the FIFA U-17 World Cup Chile 2015 with the distribution of the adidas Bronze Boot. Nwakali “Instead of player no. 8 of Nigeria, Samuel Chukwueze, the player Kelechi Nwakali (player no. 10 of Nigeria) received the adidas Bronze Boot. However, if two or more players are still equal (after goals and assists), the player who has played fewer number of minutes will be ranked first. “With this in mind, adidas will send you another Bronze Boot in December 2015, which we would kindly ask you to hand over to Samuel Chukwueze.

Erythrocyte Sedimentation Rate (ESR) Test

-
Image
1. Objective The objective of the test was to measure the rate at which red blood cells settled at the bottom of a vertical tube over a specified period, helping to detect inflammation in the body. 2. Principle The test was based on the principle that red blood cells settle faster in the presence of increased plasma proteins, such as fibrinogen and immunoglobulins, which occur during inflammation. The distance the RBCs fell in a given time was measured and expressed in millimeters per hour (mm/hr). 3. Materials • Patient’s blood sample (mixed with anticoagulant) • Westergren or Wintrobe ESR tube • Anticoagulant (sodium citrate) • ESR stand • Timer • PPE (gloves, lab coat) 4. Procedure (Microscopic/Analytical) 1. Blood was collected by venipuncture and mixed with sodium citrate anticoagulant in a 4:1 ratio. 2. The mixture was drawn into a Westergren tube up to the zero mark. 3. The tube was placed vertically in an ESR stand. 4. The level of clear plasma at the top of the col...

HIV Test

1. Objective : The objective of the HIV test was to detect antibodies, antigens, or nucleic acids of the Human Immunodeficiency Virus in order to diagnose HIV infection and monitor its stage. 2. Principle : The principle of HIV testing varied depending on the method: ELISA (Enzyme-Linked Immunosorbent Assay ): It was based on the antigen-antibody reaction where HIV antigens coated on a microplate captured patient antibodies (if present), and a color change indicated positivity. Rapid Test (ICT – Immunochromatographic Test ): It relied on antigen-antibody binding producing a visible colored line on a strip. Western Blot : It detected specific HIV proteins using patient antibodies as confirmation. PCR (Polymerase Chain Reaction ): It detected HIV RNA/DNA in blood, useful in early infection or newborns. 3. Materials : Patient’s serum or plasma sample HIV test kit (ELISA plate / Rapid strip / PCR reagents) Micropipettes and tips Buffer solution ELISA reader (for ELISA method) C...
